To match the SoC version and revision, 15 previous version patchsets had tried many methods but all of them were rejected by reviewers. Such as - dts compatible method - syscon method - ifdef PPC method - GUTS driver getting SVR method Anrd suggested a soc_device_match method in v10, and this is the only available method left now. This v11 patchset introduces the soc_device_match interface in soc driver. The first four patches of Yangbo are to add the GUTS driver. This is used to register a soc device which contain soc version and revision information. The other three patches introduce the soc_device_match method in soc driver and apply it on esdhc driver to fix this bug. --- Changes for v15: - Dropped patch 'dt: bindings: update Freescale DCFG compatible' since the work had been done by below patch on ShawnGuo's linux tree. 'dt-bindings: fsl: add LS1043A/LS1046A/LS2080A compatible for SCFG and DCFG' - Fixed error code issue in guts driver Changes for v16: - Dropped patch 'powerpc/fsl: move mpc85xx.h to include/linux/fsl' - Added a bug-fix patch from Geert --- Arnd Bergmann (1): base: soc: introduce soc_device_match() interface Geert Uytterhoeven (1): base: soc: Check for NULL SoC device attributes Yangbo Lu (5): ARM64: dts: ls2080a: add device configuration node dt: bindings: move guts devicetree doc out of powerpc directory soc: fsl: add GUTS driver for QorIQ platforms MAINTAINERS: add entry for Freescale SoC drivers mmc: sdhci-of-esdhc: fix host version for T4240-R1.0-R2.0 .../bindings/{powerpc => soc}/fsl/guts.txt | 3 + MAINTAINERS | 11 +- arch/arm64/boot/dts/freescale/fsl-ls2080a.dtsi | 6 + drivers/base/Kconfig | 1 + drivers/base/soc.c | 70 ++++++ drivers/mmc/host/Kconfig | 1 + drivers/mmc/host/sdhci-of-esdhc.c | 20 ++ drivers/soc/Kconfig | 3 +- drivers/soc/fsl/Kconfig | 18 ++ drivers/soc/fsl/Makefile | 1 + drivers/soc/fsl/guts.c | 236 +++++++++++++++++++++ include/linux/fsl/guts.h | 125 ++++++----- include/linux/sys_soc.h | 3 + 13 files changed, 447 insertions(+), 51 deletions(-) rename Documentation/devicetree/bindings/{powerpc => soc}/fsl/guts.txt (91%) create mode 100644 drivers/soc/fsl/Kconfig create mode 100644 drivers/soc/fsl/guts.c -- 2.1.0.27.g96db324
