From 910499e13387fdd025a8113f2d9fc0207eae4848 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 11 Mar 2021 16:25:32 +0100 Subject: ARM: socfpga: introduce common ARCH_INTEL_SOCFPGA Simplify 32-bit and 64-bit Intel SoCFPGA Kconfig options by having only one for both of them. This the common practice for other platforms. Additionally, the ARCH_SOCFPGA is too generic as SoCFPGA designs come from multiple vendors.

A concrete instance is that the HICRB[5:4] are for the I/O port address configurtaion of KCS channel 1/2. However, the KCS driver cannot access HICRB for channel 1/2 initialization via syscon regmap interface due to the parition boundary. (i.e. offset 80h) In addition, for the HW design backward compatibility, a newly added HW control bit could be located at any reserved one over the LPC addressing space. Thereby, this patch removes the lpc-bmc and lpc-host child node and thus the LPC partitioning. Note that this change requires the synchronization between device tree change and the driver change. To prevent the misuse of old devicetrees with new drivers, or vice versa, the v2 compatible strings are adopted for the LPC device as listed: "aspeed,ast2400-lpc-v2" "aspeed,ast2500-lpc-v2" "aspeed,ast2600-lpc-v2" Signed-off-by: Chia-Wei Wang Reviewed-by: Andrew Jeffery Link: https://lore.kernel.org/r/20210319062752.145730-2-andrew@aj.id.au Signed-off-by: Joel Stanley --- arch/arm/boot/dts/aspeed-g4.dtsi | 76 +++++++++------------- arch/arm/boot/dts/aspeed-g5.dtsi | 137 +++++++++++++++++---------------------- arch/arm/boot/dts/aspeed-g6.dtsi | 137 +++++++++++++++++---------------------- 3 files changed, 151 insertions(+), 199 deletions(-) (limited to 'arch/arm/boot/dts') diff --git a/arch/arm/boot/dts/aspeed-g4.dtsi b/arch/arm/boot/dts/aspeed-g4.dtsi index e7a45ba18fc9..c5aeb3cf3a09 100644 --- a/arch/arm/boot/dts/aspeed-g4.dtsi +++ b/arch/arm/boot/dts/aspeed-g4.dtsi @@ -343,59 +343,45 @@ };
