* pinctrl: renesas: Synchronize R-Car Gen2/Gen3 tables with Linux 5.12Marek Vasut2021-06-0712-1115/+1834
| | | | | | | | | Synchronize R-Car Gen2/Gen3 pinctrl tables with Linux 5.12, commit 9f4ad9e425a1 ("Linux 5.12") . This is a rather large commit, since the macros in sh-pfc.h also got updated, so all the PFC tables must be updated in lockstep. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
* pinctrl: single: Fix probe failure getting register area sizeVignesh Raghavendra2021-05-261-8/+2
| | | | | | | | | | | | | | | | | | If reg property of pinctrl-single node requires address translation then probe fails with following message: single-pinctrl pinctrl@4301c000: failed to get base register size This is because driver uses dev_read_addr_size() to get size which also tries to fetch untranslated addr and fails. Fix this by using dev_read_addr_size_index() which takes care of address translation and also makes following dev_read_addr() call redundant. This fixes Ethernet failures on TI's AM654 based EVMs due to lack of pinmux configuration.

* treewide: Convert macro and uses of __section(foo) to __section("foo")Marek Behún2021-05-243-3/+3
| | | | | | | | | | | | | | | | | This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

* pinctrl: renesas: Implement unlock register masksMarek Vasut2021-05-212-21/+20
| | | | | | | | | | | | | | | The V3U SoC has several unlock registers, one per register group. They reside at offset zero in each 0x200 bytes-sized block. To avoid adding yet another table to the PFC implementation, this patch adds the option to specify an address mask instead of the fixed address in sh_pfc_soc_info::unlock_reg.

Add a function for this. Update dm_gpio_set_dir_flags() to make use of this. Also update dm_gpio_set_value() to use this also, since this allows the open-drain / open-source features to be implemented directly in the driver, rather than using the uclass workaround. Update the sandbox tests accordingly. This involves a lot of changes to dm_test_gpio_opendrain_opensource() since we no-longer have the direciion being reported differently depending on the open drain/open source flags. Also update the STM32 drivers to let the uclass handle the active low/high logic. Drop the GPIOD_FLAGS_OUTPUT() macro which is no-longer used.

But the type is not updated when the pin is set as a function in sh_pfc_pinctrl_pin_set() or sh_pfc_pinctrl_group_set() calls (these calls only set the MUX if the pin type is PINMUX_TYPE_NONE ie unused). So with the current implementation pin functionality could be overwritten silently, for example if the same pin is added for SPI and serial. This patch makes sure of updating pin type after every successful call to sh_pfc_config_mux() and thus fixing from pin functionality to be overwritten. Also a warning message is printed if the current pin is being overwritten before abort. This also avoids pin re-muxing to same type that is for example from command line device is asked to re-probe/select (mmc dev x) we return early with success in this case as the pin is already muxed.
