In some cases, drivers may not want to bind to a device. Allow bind() to
return -ENODEV in this case, and don't treat this as an error. This can
be useful in situations where some information source other than the DT
node's main status property indicates whether the device should be
enabled, for example other DT properties might indicate this, or the
driver might query non-DT sources such as system fuses or a version number
register.

Introduce a new driver that supports driver model for pca953x.
The pca953x chips are used as I2C I/O expanders.
This driver is designed to support the following chips:
"
4 bits: pca9536, pca9537
8 bits: max7310, max7315, pca6107, pca9534, pca9538, pca9554,
pca9556, pca9557, pca9574, tca6408, xra1202
16 bits: max7312, max7313, pca9535, pca9539, pca9555, pca9575,
tca6416
24 bits: tca6424
40 bits: pca9505, pca9698
"
But for now this driver only supports max 24 bits and pca953x compatible
chips. pca957x compatible chips are not supported now.
These can be addressed when we need to add such support for the different
chips.
This driver has been tested on i.MX6 SoloX Sabreauto board with max7310
i2c expander using gpio command as following:
=>gpio status -a
Bank gpio@30_:
gpio@30_0: input: 1 [ ]

With this delay, now all problematic USB keys are detected successfully

Tegra20's PCIe controller has a couple of quirks. There are workarounds in
the driver for these, but they don't work after the DM conversion:
1) The PCI_CLASS value is wrong in HW.
This is worked around in pci_tegra_read_config() by patching up the value
read from that register. Pre-DM, the PCIe core always read this via a
16-bit access to the 16-bit offset 0xa. With DM, 32-bit accesses are used,
so we need to check for offset 0x8 instead. Mask the offset value back to
32-bit alignment to make this work in all cases.
2) Accessing devices other than dev 1 causes a data abort.
Pre-DM, this was worked around in pci_skip_dev(), which the PCIe core code
called during enumeration while iterating over a bus. The DM PCIe core
doesn't use this function. Instead, enhance tegra_pcie_conf_address() to
validate the bdf being accessed, and refuse to access invalid devices.
Since pci_skip_dev() isn't used, delete it.
I've also validated that both these WARs are only needed for Tegra20, by
testing on Tegra30/Cardhu and Tegra124/Jetson TKx. So, compile them in
conditionally.

The RTL8211B_driver structure in drivers/net/phy/realtek.c contains a
wrong PHY ID (0x1cc910 instead of 0x1cc912) in the uid field.
The lowest four bits of the PHY ID encode the chip revision (B+C/D/E/F)
of the RTL8211 and the code originally applied a mask of 0xfffff0 to
the PHY ID, so that matching the PHY ID to the appropriate driver code
was only done on the chip type (RTL8211), but not on a specific
revision.
After introduction of support for the RTL8211E, which needed another
startup function than the older chip revisions, commit
4220504767 changed the mask to 0xffffff
to make the chip revision relevant for the match, but didn't provide
the now-relevant lower bits of the uid field for the RTL8211B/C.
Fix this by setting the full PHY ID in the RTL8211B_driver uid field.

Add a block device cache to speed up repeated reads of block devices by
various filesystems.
This small amount of cache can dramatically speed up filesystem
operations by skipping repeated reads of common areas of a block
device (typically directory structures).
This has shown to have some benefit on FAT filesystem operations of
loading a kernel and RAM disk, but more dramatic benefits on ext4
filesystems when the kernel and/or RAM disk are spread across
multiple extent header structures as described in commit fc0fc50.
The cache is implemented through a minimal list (block_cache) maintained
in most-recently-used order and count of the current number of entries
(cache_count). It uses a maximum block count setting to prevent copies
of large block reads and an upper bound on the number of cached areas.
The maximum number of entries in the cache defaults to 32 and the maximum
number of blocks per cache entry has a default of 2, which has shown to
produce the best results on testing of ext4 and FAT filesystems.
The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows
changing these values and can be used to tune for a particular filesystem
layout.

The core part of the UniPhier pinctrl driver needs to support a new
capability for upcoming UniPhier ARMv8 SoCs. This sometimes happens
because pinctrl drivers include really SoC-specific stuff.
This commit intends to tidy up SoC-specific parameters of the existing
drivers before adding new ones. Having flags would be better than
adding new members every time a new SoC-specific capability comes up.
At this time, there is one flag, UNIPHIER_PINCTRL_CAPS_DBGMUX_SEPARATE.
This capability (I'd say rather quirk) was added for PH1-Pro4 and
PH1-Pro5 as requirement from our customer. For those SoCs, one pin-mux
setting is controlled by the combination of two separate registers; the
LSB bits at register offset (8 * N) and the MSB bits at (8 * N + 4).
Because it is impossible to update two separate registers atomically,
the LOAD_PINCTRL register should be set in order to make the pin-mux
settings really effective.

1000BASE-T master/slave autonegotiation disabled and forced to master

This is helpful for PHYs like the RTL8211C which produce unstable links
in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB
and A20-OLinuXino-Lime2.
There is no proper way to identify affected PHYs in software as the
RTL8211C shares its UID with the RTL8211B. Thus, this fix requires
the introduction of an #ifdef.

This commit solves CAAM coherency issue on ls2080. When caches are
enabled and CAAM's DMA's AXI transcations are not made cacheable,
Core reads/writes data from/to caches and CAAM does from main memory.
This forces data flushes to synchronize various data structures. But
even if any data in proximity of these structures is read by core,
these structures again are fetched in caches.
To avoid this problem, either all the data that CAAM accesses can be
made cache line aligned or CAAM transcations can be made cacheable.
So, this commit makes CAAM transcations as write back with write and
read allocate.

Implement i2c_idle_bus in driver, then setup_i2c can
be dropped for boards which enable DM_I2C/DM_GPIO/PINCTRL.
The i2c_idle_bus force bus idle flow follows setup_i2c in
arch/arm/imx-common/i2c-mxv7.c
This patch is an implementation following linux kernel patch:
"
commit 1c4b6c3bcf30d0804db0d0647d8ebeb862c6f7e5
Author: Gao Pan <b54642@freescale.com>
Date: Fri Oct 23 20:28:54 2015 +0800
i2c: imx: implement bus recovery
Implement bus recovery methods for i2c-imx so we can recover from
situations where SCL/SDA are stuck low.
Once i2c bus SCL/SDA are stuck low during transfer, config the i2c
pinctrl to gpio mode by calling pinctrl sleep set function, and then
use GPIO to emulate the i2c protocol to send nine dummy clock to recover
i2c device. After recovery, set i2c pinctrl to default group setting.
"
See Documentation/devicetree/bindings/i2c/i2c-imx.txt for detailed
description.
1. Introuduce scl_gpio/sda_gpio/bus in mxc_i2c_bus.
2. Discard the __weak attribute for i2c_idle_bus and implement it,
since we have pinctrl driver/driver model gpio driver. We can
use device tree, but not let board code to do this.
3. gpio state for mxc_i2c is not a must, but it is recommended. If
there is no gpio state, driver will give tips, but not fail.
4. The i2c controller was first probed, default pinctrl state will
be used, so when need to use gpio function, need to do
"pinctrl_select_state(dev, "gpio")" and after force bus idle,
need to switch back "pinctrl_select_state(dev, "default")".
This is example about how to use the gpio force bus
idle function:
"
&i2c1 {
clock-frequency = <100000>;
pinctrl-names = "default", "gpio";
pinctrl-0 = <&pinctrl_i2c1>;
pinctrl-1 = <&pinctrl_i2c1_gpio>;
scl-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
sda-gpios = <&gpio1 29 GPIO_ACTIVE_HIGH>;
status = "okay";
[....]
};
[.....]
pinctrl_i2c1_gpio: i2c1grp_gpio {
fsl,pins = <
MX6UL_PAD_UART4_TX_DATA__GPIO1_IO28 0x1b8b0
MX6UL_PAD_UART4_RX_DATA__GPIO1_IO29 0x1b8b0

The behavior before this patch would attempt to configure the mux
setting for pins 0 to 27 on PORTD to all be setting 3 for LVDS. The
LVDS interface actually only uses pins 18 to 27 and not pins 0 to 27
as in the parallel LCD interface. This patch restricts the
configuration to only the relevant pins 18 to 27 on PORTD.
This was tested on a sun8i A33 tablet with an LVDS screen. MMC1 has

When 'usb start' is used, block devices are created for any USB flash sticks
and disks, etc. When 'usb stop' is used, these block devices are currently
not removed.
We don't want old block devices hanging around since they can still be
visible to U-Boot. Therefore, when USB is shut down, remove and unbind all
the block devices created by the USB subsystem.
Possibly we should unbind all devices which don't cause problems by being
unbound. Most likely we can remove everything except USB controllers, hubs
and emulators. We can consider that later.

reg-offset is the part of standard 8250 binding in the kernel.
It is shifting start of address space by reg-offset.
On Xilinx platform this offset is typically 0x1000.

Add a video driver for Intel's broadwell integrated graphics controller.
This uses a binary blob for most init, with the driver just performing a few
basic tasks.
This driver supports VESA as the mode-setting mechanism. Since most boards
don't support driver model yet with VESA, a special case is added to the
Kconfig for broadwell. Eventually all boards will use driver model and this
can be removed.

We don't need this anymore - we can use device tree and the new pinconfig
driver instead.

Rather than setting up the pin configuration in the GPIO driver, use the
new pinctrl driver to do it.

At present on x86 machines with use cache-as-RAM, the memory goes away just
before board_init_r() is called. This means that serial drivers are
no-longer unavailable, until initr_dm() it called, etc.
Any attempt to use printf() within this period will cause a hang.
To fix this, mark the serial devices as 'unavailable' when it is no-longer
available. Bring it back when serial_initialize() is called. This means that
the debug UART will be used instead for this period.

If the device cannot be probed, syscon_get_by_driver_data() will still
return a useful value in its devp parameter. Ensure that it returns NULL
instead.

The Intel GPIO driver can set up the GPIO pin mapping when the first GPIO
is probed. However, it assumes that the first GPIO to be probed is in the
first GPIO bank. If this is not the case then the init will write to the
wrong registers.
Fix this. Also add a note that this code is deprecated. We should move to
using device tree instead.

It is common to read a config register value, clear and set some bits, then
write back the updated value. Add functions to do this in one step, for
convenience.
