mtd: nand: raw: convert nand_dt_init() to ofnode_xx() interface

2021-09-28T16:03:21+00:00

nand_dt_init() is still using fdtdec_xx() interface.
If OF_LIVE flag is enabled, dt property can't be get anymore.
Updating all fdtdec_xx() interface to ofnode_xx() to solve this issue.

For doing this, node parameter type must be ofnode.

First idea was to convert "node" parameter to ofnode type inside
nand_dt_init() using offset_to_ofnode(node). But offset_to_ofnode()
is not bijective, in case OF_LIVE flag is enabled, it performs an assert().

So, this leads to update nand_chip struct flash_node field from int to
ofnode and to update all nand_dt_init() callers.

mtd: spi: nor: force mtd name to "nor%d"

2021-09-28T16:03:20+00:00

Force the mtd name of spi-nor to "nor" + the driver sequence number:
"nor0", "nor1"... beginning after the existing nor devices.

This patch is coherent with existing "nand" and "spi-nand"
mtd device names.

When CFI MTD NOR device are supported, the spi-nor index is chosen after
the last CFI device defined by CONFIG_SYS_MAX_FLASH_BANKS.

When CONFIG_SYS_MAX_FLASH_BANKS_DETECT is activated, this config
is replaced by to cfi_flash_num_flash_banks in the include file
mtd/cfi_flash.h.

This generic name "nor%d" can be use to identify the mtd spi-nor device
without knowing the real device name or the DT path of the device,
used with API get_mtd_device_nm() and is used in mtdparts command.

This patch also avoids issue when the same NOR device is present 2 times,
for example on STM32MP15F-EV1:

STM32MP> mtd list
SF: Detected mx66l51235l with page size 256 Bytes, erase size 64 KiB, \
total 64 MiB

  - min I/O: 0x1 bytes
  - 0x000000000000-0x000004000000 : "mx66l51235l"

  - device: mx66l51235l@1
  - parent: spi@58003000
  - driver: jedec_spi_nor
  - path: /soc/spi@58003000/mx66l51235l@1
  - type: NOR flash

  - min I/O: 0x1 bytes
  - 0x000000000000-0x000004000000 : "mx66l51235l"

The same mtd name "mx66l51235l" identify the 2 instances
mx66l51235l@0 and mx66l51235l@1.

This patch fixes a ST32CubeProgrammer / stm32prog command issue

firmware: ti_sci: Include linux/err.h in ti_sci_protocol.h

2021-09-17T18:47:03+00:00

The common TI SCI header file uses some macros from err.h and these
get exercised when CONFIG_TI_SCI_PROTOCOL is not defined. Include
the linux/err.h header file in this header file directly rather
than relying on source files to include it to eliminate any
potential build errors.

While at this, reorder the existing header file include to the
beginning of the file.

soc: ti: pruss: Add a platform driver for PRUSS in TI SoCs

2021-07-15T12:26:04+00:00

The Programmable Real-Time Unit - Industrial Communication
Subsystem (PRU-ICSS) is present of various TI SoCs such as
AM335x or AM437x or the AM654x family. Each SoC can have
one or more PRUSS instances that may or may not be identical.

The PRUSS consists of dual 32-bit RISC cores called the
Programmable Real-Time Units (PRUs), some shared, data and
instruction memories, some internal peripheral modules, and
an interrupt controller. The programmable nature of the PRUs
provide flexibility to implement custom peripheral interfaces,
fast real-time responses, or specialized data handling.

Add support for pruss driver. Currently am654x family
is supported.

build_bug.h: add wrapper for _Static_assert

2021-07-01T20:34:32+00:00

[Linux commit 6bab69c65013bed5fce9f101a64a84d0385b3946]

BUILD_BUG_ON() is a little annoying, since it cannot be used outside
function scope.  So one cannot put assertions about the sizeof() a
struct next to the struct definition, but has to hide that in some more
or less arbitrary function.

Since gcc 4.6 (which is now also the required minimum), there is support
for the C11 _Static_assert in all C modes, including gnu89.  So add a
simple wrapper for that.

_Static_assert() requires a message argument, which is usually quite
redundant (and I believe that bug got fixed at least in newer C++
standards), but we can easily work around that with a little macro
magic, making it optional.

For example, adding

  static_assert(sizeof(struct printf_spec) == 8);

in vsprintf.c and modifying that struct to violate it, one gets

./include/linux/build_bug.h:78:41: error: static assertion failed: "sizeof(struct printf_spec) == 8"
 #define __static_assert(expr, msg, ...) _Static_assert(expr, "" msg "")

godbolt.org suggests that _Static_assert() has been support by clang
since at least 3.0.0.

mtd: spi-nor-core: Add fixups for Cypress s25hl-t/s25hs-t

2021-06-29T13:46:54+00:00

The nor->ready() and spansion_sr_ready() introduced earlier in this
series are used for multi-die package parts.

The nor->quad_enable() sets the volatile QE bit on each die.

The nor->erase() is hooked if the device is not configured to uniform
sectors, assuming it has 32 x 4KB sectors overlaid on bottom address.
Other configurations, top and split, are not supported at this point.
Will submit additional patches to support it as needed.

The post_bfpt/sfdp() fixes the params wrongly advertised in SFDP.
