clk: fractional-divider: Introduce POWER_OF_TWO_PS flag

2021-08-12T19:42:00Z

The newly introduced POWER_OF_TWO_PS flag, when set, makes the flow to skip the assumption that the caller will use an additional 2^scale prescaler to get the desired clock rate.

mfd: intel-lpss: Switch to use the software nodes

2021-04-14T15:06:11Z

Software node was always created for the device if it was supplied with additional device properties, so those nodes might as well be constant. Signed-off-by: Heikki Krogerus Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

mfd: intel-lpss: Use devm_ioremap_uc for MMIO

2019-11-11T08:40:21Z

Some BIOS erroneously specifies write-combining BAR for intel-lpss-pci in MTRR. This will cause the system to hang during boot. If possible, this bug could be corrected with a firmware update. This patch use devm_ioremap_uc to overwrite/ignore the MTRR settings by forcing the use of strongly uncachable pages for intel-lpss. The BIOS bug is present on Dell XPS 13 7390 2-in-1: [ 0.001734] 5 base 4000000000 mask 6000000000 write-combining 4000000000-7fffffffff : PCI Bus 0000:00 4000000000-400fffffff : 0000:00:02.0 (i915) 4010000000-4010000fff : 0000:00:15.0 (intel-lpss-pci) Link: https://bugzilla.kernel.org/show_bug.cgi?id=203485 Cc: # v4.19+ Tested-by: AceLan Kao Signed-off-by: Tuowen Zhao Acked-by: Mika Westerberg Acked-by: Andy Shevchenko Tested-by: Roman Gilg Signed-off-by: Lee Jones

mfd: intel-lpss: Use MODULE_SOFTDEP() instead of implicit request

2019-09-02T10:09:03Z

There is no need to handle optional module request in the driver when user space tools has that feature for ages. Replace custom code by MODULE_SOFTDEP() macro to let user space know that we would like to have the DMA driver loaded first, if any. Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

mfd: intel-lpss: Consistently use GENMASK()

2019-09-02T10:09:03Z

Since we already are using BIT() macro, use GENMASK() as well for sake of consistency. Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

Pull more clk framework updates from Stephen Boyd: "One more patch to remove io.h from clk-provider.h.

clk: Remove io.h from clk-provider.h

2019-05-15T20:21:37Z

Now that we've gotten rid of clk_readl() we can remove io.h from the clk-provider header and push out the io.h include to any code that isn't already including the io.h header but using things like readl/writel, etc. Found with this grep: git grep -l clk-provider.h | grep '.c$' | xargs git grep -L 'linux/io.h' | \ xargs git grep -l \ -e '\<__iowrite32_copy\>' --or \ -e '\<__ioread32_copy\>' --or \ -e '\<__iowrite64_copy\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__devm_memremap_pages\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__io_aw\>' --or \ -e '\<__io_pbw\>' --or \ -e '\<__io_paw\>' --or \ -e '\<__io_pbr\>' --or \ -e '\<__io_par\>' --or \ -e '\<__raw_readb\>' --or \ -e '\<__raw_readw\>' --or \ -e '\<__raw_readl\>' --or \ -e '\<__raw_readq\>' --or \ -e '\<__raw_writeb\>' --or \ -e '\<__raw_writew\>' --or \ -e '\<__raw_writel\>' --or \ -e '\<__raw_writeq\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__io_virt\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__ioremap\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' I also reordered a couple includes when they weren't alphabetical and removed clk.h from kona, replacing it with clk-provider.h because that driver doesn't use clk consumer APIs.
