treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

Pull clk updates from Stephen Boyd: "This time around we have four lines of diff in the core framework, removing a function that isn't used anymore. Otherwise the main new thing for the common clk framework is that it is selectable in the Kconfig language now. Hopefully this will let clk drivers and clk consumers be testable on more than the architectures that support the clk framework. The goal is to introduce some Kunit tests for the framework. Outside of the core framework we have the usual set of various driver updates and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the largest addition this time around in terms of lines of code. After that the x86 (Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or upcoming SoCs. After that the dirstat shows the usual suspects working on their SoC support by fixing minor bugs, correcting data and converting some of their DT bindings to YAML.

mmc: sdhci-msm: Clear tuning done flag while hs400 tuning

2020-06-01T06:04:40Z

Clear tuning_done flag while executing tuning to ensure vendor specific HS400 settings are applied properly when the controller is re-initialized in HS400 mode. Without this, re-initialization of the qcom SDHC in HS400 mode fails while resuming the driver from runtime-suspend or system-suspend.

mmc: core: Export device/vendor ids from Common CIS for SDIO cards

2020-05-29T10:38:00Z

Device/vendor ids from Common CIS (Card Information Structure) may be different as device/vendor ids from CIS on particular SDIO function. Kernel currently exports only device/vendor ids from SDIO functions and not "main" device/vendor ids from Common CIS. This patch exports "main" device/vendor ids for SDIO and SD combo cards at top level mmc device in sysfs hierarchy. Userspace can use e.g. udev rules to correctly match whole SDIO card based on Common CIS device/vendor id and not only one particular SDIO function. Having this information in userspace also helps developers to debug whole SDIO card as e.g. kernel mmc quirks use device/vendor ids from Common CIS and not from particular SDIO function. Also it allows to write userspace applications which list all connected SDIO cards based on CIS ids.

mmc: sdhci-esdhc-imx: disable the CMD CRC check for standard tuning

2020-05-29T10:38:00Z

In current code, we add 1ms dealy after each tuning command for standard tuning method. Adding this 1ms dealy is because USDHC default check the CMD CRC and DATA line. If detect the CMD CRC, USDHC standard tuning IC logic do not wait for the tuning data sending out by the card, trigger the buffer read ready interrupt immediately, and step to next cycle. So when next time the new tuning command send out by USDHC, card may still not send out the tuning data of the upper command，then some eMMC cards may stuck, can't response to any command, block the whole tuning procedure. If do not check the CMD CRC for tuning, then do not has this issue. USDHC will wait for the tuning data of each tuning command and check them. If the tuning data pass the check, it also means the CMD line also okay for tuning. So this patch disable the CMD CRC check for tuning, save some time for the whole tuning procedure.
