[ Upstream commit 02181e68275d28cab3c3f755852770367f1bc229 ]

Driver moxart-mmc.c has .compatible = "moxa,moxart-mmc".

But moxart .dts/.dtsi and the documentation file moxa,moxart-dma.txt
contain compatible = "moxa,moxart-sdhci".

Change moxart .dts/.dtsi files and moxa,moxart-dma.txt to match the driver.

Replace 'sdhci' with 'mmc' in names too, since SDHCI is a different
controller from FTSDC010.

regulator: s5m8767: do not use reset value as DVS voltage if GPIO DVS is disabled 2021-11-26T10:40:23+00:00 Krzysztof Kozlowski krzysztof.kozlowski@canonical.com 2021-10-08T11:37:13+00:00 56b930d017d0d61146bea5fe80255e6cc1b72602 commit b16bef60a9112b1e6daf3afd16484eb06e7ce792 upstream. The driver and its bindings, before commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") were requiring to provide at least one safe/default voltage for DVS registers if DVS GPIO is not being enabled. IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

The driver and its bindings, before commit 04f9f068a619 ("regulator:

requiring to provide at least one safe/default voltage for DVS registers

This requirement was coming from driver behavior matching this condition
(none of DVS GPIO is enabled): it was always initializing the DVS
selector pins to 0 and keeping the DVS enable setting at reset value
(enabled).  Therefore if none of DVS GPIO is enabled in devicetree,
driver was configuring the first DVS voltage for buck[234].

Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing

won't be parsed from devicetree if DVS GPIO is not enabled.  After the
change, driver will configure bucks to use the register reset value as
voltage which might have unpleasant effects.
