Reset controller updates for v5.19 Add Meson-S4 SoC reset controller support to reset-meson, AST2600 LPC reset controller support to reset-simple, and R9A07G054 USBPHY reset controller support to reset-rzg2l-usbphy-ctrl. Add ACPI _RST support to device_reset(), simplify the uniphier-glue reset driver using bulk API and devres and clean up its dt-bindings docs. Convert most dt-bindings docs from txt to yaml. * tag 'reset-for-v5.19' of git://git.pengutronix.de/pza/linux: dt-bindings: reset: st,sti-powerdown: Convert to yaml dt-bindings: reset: st,sti-picophyreset: Convert to yaml dt-bindings: reset: socfpga: Convert to yaml dt-bindings: reset: snps,axs10x-reset: Convert to yaml dt-bindings: reset: nuvoton,npcm-reset: Convert to yaml dt-bindings: reset: lantiq,reset: Convert to yaml dt-bindings: reset: bitmain,bm1880-reset: Convert to yaml dt-bindings: reset: berlin: Convert to yaml dt-bindings: reset: ath79: Convert to yaml dt-bindings: reset: amlogic,meson-axg-audio-arb: Convert to yaml dt-bindings: reset: uniphier-glue: Clean up clocks, resets, and their names using compatible string reset: Kconfig: Make RESET_RZG2L_USBPHY_CTRL depend on ARCH_RZG2L reset: ACPI reset support reset: simple: Add AST2600 compatible reset: reset-meson: add support for the Meson-S4 SoC Reset Controller dt-bindings: reset: add bindings for the Meson-S4 SoC Reset Controller dt-bindings: reset: Add compatible for Meson-S4 Reset Controller reset: uniphier-glue: Use devm_add_action_or_reset() reset: uniphier-glue: Use reset_control_bulk API Link: https://lore.kernel.org/r/20220503160057.46625-1-p.zabel@pengutronix.de Signed-off-by: Arnd Bergmann

reset: Kconfig: Make RESET_RZG2L_USBPHY_CTRL depend on ARCH_RZG2L

2022-05-03T15:41:28Z

The USBPHY Control block is identical on Renesas RZ/G2L and RZ/V2L SoC's, so instead of adding dependency for each SoC's add dependency on ARCH_RZG2L. The ARCH_RZG2L config option is already selected by ARCH_R9A07G044 and ARCH_R9A07G054.

reset: ACPI reset support

2022-05-03T15:41:25Z

Some of the IO devices like I2C or SPI require reset at runtime to recover from an error condition without changing the power state of the system. Added check for ACPI handle and a call to method '__RST' if supported. Devices using device tree method are unaffected by this.

reset: simple: Add AST2600 compatible

2022-05-03T15:40:51Z

Similar to the 2400 and 2500, the LPC controller has some simple reset lines that are used by the UART devices. This is already documented in LPC bindings document. Signed-off-by: Joel Stanley Signed-off-by: Philipp Zabel Link: https://lore.kernel.org/r/20220221072650.129348-1-joel@jms.id.au

reset: reset-meson: add support for the Meson-S4 SoC Reset Controller

2022-05-03T15:40:51Z

Compared to the A1 SoCs the number of RESET registers is different and the offset for the level registers is the same. Add a new compatible string and struct meson_reset_param to add support for the reset controller on the S4 SoC.

reset: uniphier-glue: Use reset_control_bulk API

reset: tegra-bpmp: Restore Handle errors in BPMP response

2022-04-04T09:14:13Z

This reverts following commit 69125b4b9440 ("reset: tegra-bpmp: Revert Handle errors in BPMP response"). The Tegra194 HDA reset failure is fixed by commit d278dc9151a0 ("ALSA: hda/tegra: Fix Tegra194 HDA reset failure"). The temporary revert of original commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP response") can be removed now.
