2020-10-30arm64: dts: imx8mn-ddr4-evk: fix missing PMIC's interrupt line pull-upKrzysztof Kozlowski1-0/+1
The PMIC's interrupt is level low and should be pulled up. The PMIC's device node had pinctrl-0 property but it lacked pinctrl-names which is required to apply the pin configuration. Fixes: 4153f7811a9b ("arm64: dts: imx8mn: correct interrupt flags") Fixes: 3e44dd09736d ("arm64: dts: imx8mn-ddr4-evk: Add rohm,bd71847 PMIC support") Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Reviewed-by: Robin Gong <yibin.gong@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2020-09-22arm64: dts: imx8mn: correct interrupt flagsKrzysztof Kozlowski1-1/+1
GPIO_ACTIVE_x flags are not correct in the context of interrupt flags. These are simple defines so they could be used in DTS but they will not have the same meaning: 1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE 2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING Correct the interrupt flags, assuming the author of the code wanted same logical behavior behind the name "ACTIVE_xxx", this is: ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW For level low interrupts, enable also internal pull up. It is required at least on imx8mm-evk, according to schematics.

2020-09-05arm64: dts: imx8mn-ddr4-evk: Align regulator names with schemaKrzysztof Kozlowski1-11/+11
Device tree schema expects regulator names to be lowercase. Changing to lowercase has multiple effects: 1. LDO6 supply is now properly configured, because regulator driver looks for supplies by lowercase name, 2. User-visible names via sysfs or debugfs are now lowercase, 2. dtbs_check warnings are fixed: pmic@4b: regulators:LDO1:regulator-name:0: 'LDO1' does not match '^ldo[1-6]$' Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Acked-By: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2020-09-05arm64: dts: imx8mm-ddr4-evk: Align pin configuration group names with schemaKrzysztof Kozlowski1-1/+1
Device tree schema expects pin configuration groups to end with 'grp' suffix, otherwise dtbs_check complain with a warning like: ... do not match any of the regexes: 'grp$', 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2020-06-18arm64: dts: imx8mn-ddr4-evk: correct ldo1/ldo2 voltage rangeRobin Gong1-2/+2
Correct ldo1 voltage range from wrong high group(3.0V~3.3V) to low group (1.6V~1.9V) because the ldo1 should be 1.8V. Actually, two voltage groups have been supported at bd718x7-regulator driver, hence, just corrrect the voltage range to 1.6V~3.3V. For ldo2@0.8V, correct voltage range too. Otherwise, ldo1 would be kept @3.0V and ldo2@0.9V which violate i.mx8mn datasheet as the below warning log in kernel: [ 0.995524] LDO1: Bringing 1800000uV into 3000000-3000000uV [ 0.999196] LDO2: Bringing 800000uV into 900000-900000uV Fixes: 3e44dd09736d ("arm64: dts: imx8mn-ddr4-evk: Add rohm,bd71847 PMIC support") Cc: stable@vger.kernel.org Signed-off-by: Robin Gong <yibin.gong@nxp.com> Reviewed-by: Dong Aisheng <aisheng.dong@nxp.com> Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

This is used by the imx-ddrc devfreq driver to implement dynamic frequency scaling of DRAM. Support for proactive scaling via interconnect will come later. The high-performance bus masters which need that (display, vpu, gpu) are mostly not yet enabled in upstream anyway.
