Texas Instrument's TPS65910 PMIC contains 3 buck DC-DC converts, one
boost DC-DC converter and 8 LDOs. This patch implements driver model
support for the TPS65910 PMIC and its regulators making the get/set
API for regulator value/enable available.
This patch depends on the patch "am33xx: Add a function to query MPU
voltage in uV" to build correctly. For boards relying on the DT
include file tps65910.dtsi the v3 patch "power: extend prefix match
to regulator-name property" and an appropriate regulator naming is
also required.Signed-off-by: Felix Brack

This patch changes the calls to uclass_first/next_device() in blk_first/
next_device() to use uclass_find_first/next_device() instead. These functions
don't prepare the devices, which is correct in this case.With this patch applied, the "usb storage" command now works again as
expected:=> usb storage

This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.Signed-off-by: Felix Brack

The DM version of do_reset has been issuing a warm-reset, which (on
some platforms keeps GPIOs and other parts of the platform active).
This may cause unintended behaviour, as calling do_reset usually
indicates a desire to reset the board/platform and not just the CPU.This changes do_reset to always request a COLD reset.
Note that programmatic uses can still invoke a WARM reset through
reset_cpu() or using sysreset_walk().Signed-off-by: Philipp Tomsich

This driver really is DM GPIO one and so we need to have a correct
dependency, because DM alone doesn't provide required for CMD_GPIO
call and we're seeing build failures like this:

Synopsys HSDK clock controller generates and supplies clocks to various
controllers and peripherals within the SoC.Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the
dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device
tree sources.Signed-off-by: Eugeniy Paltsev

The .probe_chip function is supposed to probe an i2c device on the bus to
determine whether a device is answering to a particular address.
at91_i2c_probe_chip() did not do anything resembling this and always
returned 0.It looks as though at91_i2c_probe_chip() was intended to be a .probe
function for the controller, as it was copied-and-pasted to become
at91_i2c_probe() in 0bc8f640a4d7ed.Removing the at91_i2c_probe_chip() function makes the higher layer
(i2c_probe_chip()) try a zero-length read transfer to test for the
presence of a device instead, which does work.Signed-off-by: Alan Ott

The driver must wait for TXRDY after each byte is pushed into
the i2c FIFO before pushing the next byte. Previously this was
not done for the first byte, causing a race condition with zeros
sometimes being sent for the next byte (which is typically the
first actual data byte).Signed-off-by: Alan Ott

Existing MC driver framework is based on MC-9.x.x flib. This patch
migrates MC obj (DPBP, DPNI, DPRC, DPMAC etc) to use latest MC flib
which is MC-10.3.0.Changes introduced due to migration:
1. To get OBJ token, pair of create and open API replaces create APIs
2. Pair of close and destroy APIs replaces destroy APIs
3. For version read, get_version APIs replaces get_attributes APIs
4. dpni_get/reset_statistics APIs replaces dpni_get/set_counter APIs
5. Simplifies struct dpni_cfg and removes dpni_extended_cfg struct
6. Single API dpni_get_buffer_layout/set_buffer_layout replaces
dpni_get_rx/set_rx, tx related, tx_conf_buffer_layout related APIs.
New API takes a queue type as an argument.
7. Similarly dpni_get_queue/set_queue replaces
dpni_get_rx_flow/set_rx_flow , tx_flow related, tx_conf related
APIsSigned-off-by: Yogesh Gaur

We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.Signed-off-by: Masahiro Yamada

Commit 72443c7f7d21 ("mtd: cfi: Add support for status register
polling") added a feature check to determine if status register
is available for certain flash chips. The "lower software bits"
register used to determine this feature is not backward compati-
ble. Older flash chips without this feature has reserved value
0xff. Instead of checking "lower software bits" register, use
CFI primary vendor-specific extended query. Since CFI version
1.4, software features can be read from offset 0x53 according to
document AN201168 from Cypress.Signed-off-by: York Sun
