Hi, this series come from my discussion with Arnd at KS and then on some other threads/IRCs(Arnd and Mark) that SoC vendors are more and more try to add misc functionality to one memory region. For this purpose syscon driver is in the kernel. But regular syscon driver is initialized too late and platforms are trying to create specific code to handle it. For this purpose the series have been created to provide early syscon initialization and regmap creation first and then attaching device. The last patch is zynq specific patch to clear slcr driver and clock driver can profit from it too when clk regmap is ready. Also moving syscon driver from mfs should be consider. Mark already applied the first part to his regmap repo git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git tags/nodev Thanks for your comments, Michal Changes in v2: - Fix bad logic in early_syscon_probe - Fix compilation failure for x86_64 reported by zero day testing system - Regmap change available here git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git tags/nodev Michal Simek (2): mfd: syscon: Support early initialization ARM: zynq: Use early syscon initialization arch/arm/boot/dts/zynq-7000.dtsi | 1 + arch/arm/mach-zynq/common.c | 6 +- arch/arm/mach-zynq/slcr.c | 42 +------------ drivers/clk/zynq/clkc.c | 57 ++++++----------- drivers/mfd/syscon.c | 128 +++++++++++++++++++++++++++++++++------ include/linux/mfd/syscon.h | 11 ++++ 6 files changed, 145 insertions(+), 100 deletions(-) -- 1.8.2.3
