commit d7a83d67a1694c42cc95fc0755d823f7ca3bfcfb upstream. Use usbs_mask passed as argument. The usbs_mask is different for SAM9X60.

2020-04-17T14:12:16+00:00

commit edcc42945dee85e9dec3737f3dbf59d917ae5418 upstream. When requesting a rate superior to the parent's rate, it would return -EINVAL instead of simply returning the parent's rate like it should.

commit c067b46d731a764fc46ecc466c2967088c97089e upstream. Exit jz4770_cgu_init() if the 'cgu' pointer we get is NULL, since the pointer is passed as argument to functions later on.

clk: ti: am43xx: Fix clock parent for RTC clock

commit 5f3d9b07b9bb4679922f0b2e2baa770e74a6bbd3 upstream. Currently enabling clkctrl clock on am4 can fail for RTC as the clock parent is wrong for RTC.

clk: imx: Align imx sc clock parent msg structs to 4

2020-04-02T13:09:53+00:00

commit 8400ab8896324641243b57fc49b448023c07409a upstream. The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y. Fix by marking with __aligned(4).

clk: uniphier: Add SCSSI clock gate for each channel

2020-02-24T07:38:22+00:00

[ Upstream commit 1ec09a2ec67a0baa46a3ccac041dbcdbc6db2cb9 ] SCSSI has clock gates for each channel in the SoCs newer than Pro4, so this adds missing clock gates for channel 1, 2 and 3. And more, this moves MCSSI clock ID after SCSSI.

clk: Use parent node pointer during registration if necessary

2020-02-24T07:38:22+00:00

[ Upstream commit 9011f92622e5ef2d075f45e5fa818776d4feb8c0 ] Sometimes clk drivers are attached to devices which are children of a parent device that is connected to a node in DT. This happens when devices are MFD-ish and the parent device driver mostly registers child devices to match against drivers placed in their respective subsystem directories like drivers/clk, drivers/regulator, etc. When the clk driver calls clk_register() with a device pointer, that struct device pointer won't have a device_node associated with it because it was created purely in software as a way to partition logic to a subsystem. This causes problems for the way we find parent clks for the clks registered by these child devices because we look at the registering device's device_node pointer to lookup 'clocks' and 'clock-names' properties. Let's use the parent device's device_node pointer if the registering device doesn't have a device_node but the parent does. This simplifies clk registration code by avoiding the need to assign some device_node to the device registering the clk.
