soc: rockchip: Fix refcount leak in rockchip_grf_init

2022-06-14T16:44:50Z

[ Upstream commit 9b59588d8be91c96bfb0371e912ceb4f16315dbf ] of_find_matching_node_and_match returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.

dtpm/soc/rk3399: Add the ability to unload the module

2022-02-23T18:46:29Z

The dtpm hierarchy can now be removed with the dtpm_destroy_hierarchy() function. Add the module_exit() callback so the module can be unloaded by removing the previously created hierarchy.

rockchip/soc/drivers: Add DTPM description for rk3399

2022-02-04T16:38:09Z

The DTPM framework does support now the hierarchy description. The platform specific code can call the hierarchy creation function with an array of struct dtpm_node pointing to their parent. This patch provides a description of the big / Little CPUs and the GPU and tie them together under a virtual 'package' name. Only rk3399 is described now. The description could be extended in the future with the memory controller with devfreq. The description is always a module and it describes the soft dependencies. The userspace has to load the softdeps module in the right order.

soc: rockchip: io-domain: add rk3568 support

2021-08-14T06:23:47Z

The io-domain registers on RK3568 SoCs have three separated bits to enable/disable the 1.8v/2.5v/3.3v power. This patch make the write to be a operation, allow rk3568 uses a private register set function. Since the 2.5v mode hasn't been fully validated yet, the driver only sets 1.8v [enable] + 3.3v [disable] for 1.8v mode 1.8v [disable] + 3.3v [enable] for 3.3v mode There is not register order requirement which has been cleared by our IC team. For future reference the full usage matrix including the 2.5V setting is: case V33 V25 V18 result 0 0 0 0 IO safe, but cannot work 1 0 0 1 IO require 1.8V, should < 1.98V, otherwise IO may damage 2 0 1 0 IO require 2.5V, should < 2.75V, otherwise IO may damage 3 0 1 1 Invalid state, should avoid 4 1 0 0 IO require 3.3V, should < 3.63V, otherwise IO may damage 5 1 0 1 IO require 1.8V, should < 1.98V, otherwise IO may damage 6 1 1 0 IO require 2.5V, should < 2.75V, otherwise IO may damage 7 1 1 1 Invalid state, should avoid Signed-off-by: Jianqun Xu Tested-by: Peter Geis [added mode clarification from Jay] Link: https://lore.kernel.org/r/20210805120107.27007-3-michael.riesch@wolfvision.net Signed-off-by: Heiko Stuebner
