Subject: [PATCH] dt-bindings: clock: Document clock and reset unit of RK3528
There are two types of clocks in RK3528 SoC, CRU-managed and
SCMI-managed. Independent IDs are assigned to them.
For the reset part, differing from previous Rockchip SoCs and
downstream bindings which embeds register offsets into the IDs, gapless
numbers starting from zero are used.

+title: Rockchip RK3528 Clock and Reset Controller
+
+maintainers:
+ - Yao Zi <ziyao@disroot.org>
+
+description: |
+ The RK3528 clock controller generates the clock and also implements a reset
+ controller for SoC peripherals. For example, it provides SCLK_UART0 and
+ PCLK_UART0 as well as SRST_P_UART0 and SRST_S_UART0 for the first UART
+ module.
+ Each clock is assigned an identifier, consumer nodes can use it to specify
+ the clock. All available clock and reset IDs are defined in dt-binding
+ headers.

Subject: [PATCH] clk: rockchip: Add PLL flag ROCKCHIP_PLL_FIXED_MODE
RK3528 comes with a new PLL variant: its "PPLL", which mainly generates
clocks for the PCIe controller, operates in normal mode only. Let's
describe it with flag ROCKCHIP_PLL_FIXED_MODE and handle it in code.

Subject: [PATCH] clk: rockchip: rk3528: Add reset lookup table
In the commit 5d0eb375e685 ("clk: rockchip: Add clock controller driver
for RK3528 SoC") only the dt-binding header was added for the reset
controller for the RK3528 SoC.
Add a reset lookup table generated from the SRST symbols used by vendor
linux-6.1-stan-rkr5 kernel to complete support for the reset controller.

region
These clocks locate in VO and VPU GRF, serving for SD/SDIO controller
tuning purpose. Add their definitions and register them in driver if
corresponding GRF is available.
GRFs are looked up by compatible to simplify devicetree binding.

Subject: [PATCH] clk: rockchip: rk3528: add slab.h header include
The newly added GRF types introduced kzalloc usage into the rk3528.
At least for the similar rk3576 driver, the kernel-test-robot reported the
missing prototype, which warranted adding a slab.h include.
While it did not complain about the rk3528, so the header might be included
"accidentially" right now, add a real include to make sure we keep it
included in the future.

Subject: [PATCH] phy: rockchip: naneng-combphy: Add SoC prefix to register
definitions
All supported variants of naneng-combphy follow a register layout
similar to the RK3568 variant with some exceptions of SoC-specific
registers.
Add RK3568 prefix for the common set of registers and the corresponding
SoC prefix for SoC-specific registers, making usage of definitions clear
and preparing for future COMBPHY variants with a different register
layout.

Subject: [PATCH] phy: rockchip: naneng-combphy: Add RK3528 support
Rockchip RK3528 integrates one naneng-combphy that is able to operate in
PCIe and USB3 mode. The control logic is similar to previous variants of
naneng-combphy but the register layout is apparently different from the
RK3568 one.

Subject: [PATCH] iio: adc: rockchip_saradc: Add support for RK3528
The Successive Approximation ADC (SARADC) in RK3528 uses the v2
controller and support:
- 10-bit resolution
- Up to 1MS/s sampling rate
- 4 single-ended input channels
- Current consumption: 0.5mA @ 1MS/s
Add support for the 4 channels of 10-bit resolution supported by SARADC
in RK3528.

Subject: [PATCH] net: stmmac: dwmac-rk: Move integrated_phy_powerup/down
functions
Rockchip RK3528 (and RV1106) has a different integrated PHY compared to
the integrated PHY on RK3228/RK3328. Current powerup/down operation is
not compatible with the integrated PHY found in these SoCs.
Move the rk_gmac_integrated_phy_powerup/down functions to top of the
file to prepare for them to be called directly by a GMAC variant
specific powerup/down operation.

From 41f35564cb71e7043e0afcf30078b4a6145cab64 Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: stmmac: dwmac-rk: Remove unneeded GRF and peripheral GRF
checks
Now that GRF, and peripheral GRF where needed, is validated at probe
time there is no longer any need to check and log an error in each SoC
specific operation.
Remove unneeded IS_ERR() checks and early bail out from each SoC
specific operation.
