737dbd66 - PM / devfreq: Remove "select SRCU"

Thu, 05 Jan 2023 00:37:58 +0000

PM / devfreq: Remove "select SRCU"Now that the SRCU Kconfig option is unconditionally selected, there isno longer any point in selecting it. Therefore, remove the "select SRCU"Kconfig statements.Signed-off-by: Paul E. McKenney Signed-off-by: Chanwoo Choi List of files: /linux-6.15/drivers/devfreq/Kconfig

86d231b1 - PM / devfreq: mediatek: Introduce MediaTek CCI devfreq driver

Tue, 07 Jun 2022 14:05:56 +0000

PM / devfreq: mediatek: Introduce MediaTek CCI devfreq driverWe introduce a devfreq driver for the MediaTek Cache Coherent Interconnect(CCI) used by some MediaTek SoCs.In this driver, we use the passive devfreq driver to get target frequenciesand adjust voltages accordingly. In MT8183 and MT8186, the MediaTek CCIis supplied by the same regulators with the little core CPUs.Signed-off-by: Jia-Wei Chang Signed-off-by: Johnson Wang Acked-by: Chanwoo Choi Tested-by: Kevin Hilman Signed-off-by: Chanwoo Choi List of files: /linux-6.15/drivers/devfreq/Kconfig

8bfd4858 - PM / devfreq: Add a driver for the sun8i/sun50i MBUS

Thu, 18 Nov 2021 03:18:41 +0000

PM / devfreq: Add a driver for the sun8i/sun50i MBUSThis driver works by adjusting the divider on the DRAM controller'smodule clock. Thus there is no fixed set of OPPs, only "full speed" downto "quarter speed" (or whatever the maximum divider is on that variant).It makes use of the MDFS hardware in the MBUS, in "DFS" mode, whichtakes care of updating registers during the critical section while DRAMis inaccessible.This driver should support several sunxi SoCs, starting with the A33,which have a DesignWare DDR3 controller with merged PHY register spaceand the matching MBUS register layout (so not A63 or later). However,the driver has only been tested on the A64/H5, so those are the onlycompatibles enabled for now.Acked-by: Chanwoo Choi Signed-off-by: Samuel Holland Signed-off-by: Chanwoo Choi List of files: /linux-6.15/drivers/devfreq/Kconfig

PM / devfreq: tegra20: Deprecate in a favor of emc-stat based driverRemove tegra20-devfreq in order to replace it with a EMC_STAT baseddevfreq driver. Previously we were going to use MC_STAT basedtegra20-devfreq driver because EMC_STAT wasn't working properly, butnow that problem is resolved. This resolves complications imposed bythe removed driver since it was depending on both EMC and MC driverssimultaneously.Acked-by: Chanwoo Choi Signed-off-by: Dmitry Osipenko Signed-off-by: Chanwoo Choi List of files: /linux-6.15/drivers/devfreq/Kconfig

cc2a4e83 - PM / devfreq: tegra20: Relax Kconfig dependency

Sun, 25 Oct 2020 22:17:31 +0000

PM / devfreq: tegra20: Relax Kconfig dependencyThe Tegra EMC driver now could be compiled as a loadable kernel module.Currently devfreq driver depends on the EMC/MC drivers in Kconfig, andthus, devfreq is forced to be a kernel module if EMC is compiled as amodule. This build dependency could be relaxed since devfreq driverchecks MC/EMC presence on probe, allowing kernel configuration wheredevfreq is a built-in driver and EMC driver is a loadable module.This change puts Tegra20 devfreq Kconfig entry on a par with the Tegra30devfreq entry.Acked-by: Chanwoo Choi Signed-off-by: Dmitry Osipenko Signed-off-by: Chanwoo Choi List of files: /linux-6.15/drivers/devfreq/Kconfig

5af744eb - PM / devfreq: Add dynamic scaling for imx8m ddr controller

Fri, 22 Nov 2019 21:45:03 +0000

PM / devfreq: Add dynamic scaling for imx8m ddr controllerAdd driver for dynamic scaling the DDR Controller on imx8m chips. Actualfrequency switching is implemented inside TF-A, this driver wraps theSMC calls and synchronizes the clk tree.The DRAM clocks on imx8m have the following structure (abridged): +----------+ |\ +------+ | dram_pll |-------|M| dram_core | | +----------+ |U|---------->| D | /--|X| | D | dram_alt_root | |/ | R | | | C | +---------+ | | |FIX DIV/4| | | +---------+ | | composite: | | | +----------+ | | | | dram_alt |----/ | | +----------+ | | | dram_apb |-------------------->| | +----------+ +------+The dram_pll is used for higher rates and dram_alt is used for lowerrates. The dram_alt and dram_apb clocks are "imx composite" and theirparent can also be modified.This driver will prepare/enable the new parents ahead of switching (sothat the expected roots are enabled) and afterwards it will callclk_set_parent to ensure the parents in clock framework are up-to-date.The driver relies on dram_pll dram_alt and dram_apb being marked withCLK_GET_RATE_NOCACHE for rate updates.Signed-off-by: Leonard Crestez Acked-by: Chanwoo Choi [cw00.choi: Edit the COMPILE_TEST module dependency in Kconfig]Signed-off-by: Chanwoo Choi List of files: /linux-6.15/drivers/devfreq/Kconfig
