* treewide: fix typos of SPDX-License-IdentifierMasahiro Yamada2019-06-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to the adoption of SPDX, it was difficult for tools to determine the correct license due to incomplete or badly formatted license text. The SPDX solves this issue, assuming people can correctly spell "SPDX-License-Identifier" although this assumption is broken in some places. Since scripts/spdxcheck.py parses only lines that exactly matches to the correct tag, it cannot (should not) detect this kind of error. If the correct tag is missing, scripts/checkpatch.pl warns like this: WARNING: Missing or malformed SPDX-License-Identifier tag in line * So, people should notice it before the patch submission, but in reality broken tags sometimes slip in. The checkpatch warning is not useful for checking the committed files globally since large number of files still have no SPDX tag. Also, I am not sure about the legal effect when the SPDX tag is broken. Anyway, these typos are absolutely worth fixing. It is pretty easy to find suspicious lines by grep. $ git grep --not -e SPDX-License-Identifier --and -e SPDX- -- \ :^LICENSES :^scripts/spdxcheck.py :^*/license-rules.rst arch/arm/kernel/bugs.c:// SPDX-Identifier: GPL-2.0 drivers/phy/st/phy-stm32-usbphyc.c:// SPDX-Licence-Identifier: GPL-2.0 drivers/pinctrl/sh-pfc/pfc-r8a77980.c:// SPDX-Lincense-Identifier: GPL 2.0 lib/test_stackinit.c:// SPDX-Licenses: GPLv2 sound/soc/codecs/max9759.c:// SPDX-Licence-Identifier: GPL-2.0 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | This patch adds I2C{0,3,5} pins, groups and functions to the R8A7796 SoC. These pins are physically muxed with other pins. Therefore, setup of MOD_SEL is needed for exclusive control with other pins.

For now the following checks are included: - Check register and field widths in descriptors for config registers with variable-width fields, - Check relations between pin groups and functions: - All pin functions must refer to existing pin groups, - All pin groups must be referred to by a pin function, - Warn if a pin group is referred to by multiple pin functions (which is OK for backwards-compatibility aliases), - Provide suggestions for reducing table sizes: reserved fields of more than 3 bits can better be split in smaller subfields, as the storage need is proportional to the square of the width of the (sub)field, Note that a dummy non-matching entry is added to the DT match table for checking r8a7795es1_pinmux_info, as R-Car H3 ES1.0 is matched using soc_device_match() in r8a7795_pinmux_init(), instead of by the DT match table.

Increase consistency with other SoCs by making R-Car M2-W and M2-N, and RZ/G1M and RZ/G1N, use the recently added optional "version" argument of the VIN_DATA_PIN_GROUP() macro. Note that this breaks backwards compatibility with existing DTBs, but there are no upstream users of the "vin1_b_*" names.

| | | | | | | | | | | | | | Documentation for ES1.0 says that some bits in TDSEL must be set (ch 5.3.35 in R-Car E2 v0.5). However, the reset value of the register is 0, so software has to do it. Add this to the kernel driver to ensure this is really done independent of firmware versions and use whitelisting for ES versions known to need this. This is needed for some SD cards supporting SDR104 transfer mode.

| | | | | | | | | | | | | | | | Documentation for ES1.0 says that some bits in TDSEL must be set (ch 5.3.39 in R-Car H2 v0.91). However, the reset value of the register is 0, so software has to do it. Add this to the kernel driver to ensure this is really done independent of firmware versions and use whitelisting for ES versions known to need this. This is needed for some SD cards supporting SDR104 transfer mode. For me, TDSEL was not initialized by the firmware and I had problems with the card when re-inserting it.
