soc: imx: Break dependency on SOC_IMX8MQ for GPCv2

2019-01-14T01:42:22Z

Since this is going to be used on more SoCs than just i.MX8MQ, make the dependency here more generic by using ARCH_MXC instead. Also remove the SOC_IMX7D since it is also included by the ARCH_MXC. Signed-off-by: Abel Vesa Reviewed-by: Dong Aisheng Signed-off-by: Shawn Guo

soc: imx: gpcv2: handle reset clocks

2019-01-11T07:12:59Z

Some power domains handled by the GPCv2 driver need to enable the clocks for devies inside the domain, so that the reset propagation and proper power-up sequencing happens. Handle them in the same way as on GPCv1. Signed-off-by: Lucas Stach Acked-by: Rob Herring Signed-off-by: Shawn Guo

soc: imx: gpcv2: handle additional power-down bits in handshake register

2019-01-11T07:12:38Z

Some of the i.MX8MQ domains have an additional control bit in the PU handshake (HSK) register. Documentation about this bit is a bit sparse at the moment, but it seems that it controls a power-down request to the AMBA domain bridge (ADB-400) attached to those domains. As the documentation doesn't desribe the usage of this bit yet, handle it in the same way as done in the ATF implementation. Signed-off-by: Lucas Stach Signed-off-by: Shawn Guo

soc: imx: gpc: Increase GPC_CLK_MAX to 7

The DISPLAY power domain on imx6sx has 7 clocks. Signed-off-by: Leonard Crestez Signed-off-by: Shawn Guo

soc: imx: gpcv2: add support for i.MX8MQ SoC

2018-12-05T00:50:36Z

The GPCv2 on the Freescale i.MX8MQ SoC works in the same way as the GPCv2 on the i.MX7, but only controls more power domains with a different mapping. Signed-off-by: Lucas Stach Acked-by: Rob Herring Signed-off-by: Shawn Guo

soc: imx: gpcv2: move register access table to domain data

2018-12-05T00:50:34Z

The valid register ranges are defined by the implemented power domains, which are different between the individual SoCs where the GPCv2 is used. Signed-off-by: Lucas Stach Signed-off-by: Shawn Guo

soc: imx: gpcv2: prefix i.MX7 specific defines

2018-12-05T00:50:19Z

So we can add i.MX8M support without introducing name clashes. Signed-off-by: Lucas Stach Signed-off-by: Shawn Guo

soc: imx: gpcv2: make pgc driver more generic for other i.MX platforms

2018-10-01T05:24:14Z

i.MX8MQ and i.MX8MM share same gpc module with i.MX7D, they can reuse gpcv2 pgc driver for power domain control, this patch renames all functions and structure definitions started with "imx7" to "imx", and use .data in imx_gpcv2_dt_ids[] to pass platform specific power domain data for power domain driver, thus make gpcv2 pgc driver more generic for i.MX platforms.
