Update imx8 clock driver to support LPCG and full clocks tree for some modules aligned with kernel.
We classify the clock into serveral types: slice, fixed, lpcg, gpr and mux. Generally slice and fixed clocks are the sources. lpcg, gpr and mux are the downstream of those sources and are used for gating, muxing or dividing functions.
This patch replaces the functions defined in imx8qm and imx8qxp with the clock tables of different clock types. clk-imx8 use unified functions to process these clock tables.
Note: since the clock depends on the power domain of its resource, must power on the resource firstly, then we can get the clock. Otherwise, we can't access lpcg. Thus, the clock dump only works for the slice clock.

Hi All,
Subject: [PATCH v2 3/7] clk: imx8: Update imx8 clock driver
Sorry to bring back this topic.
This patch is not converting to CCF following Linux, but it could satisfy u-boot usage and make more feature work.
I checked Linux i.MX8 CCF recently, although Linux upstream has i.MX8 CCF support, but NXP downstream has significantly reimplement the code. So we could not take code directly from Linux upstream, because this would introduce efforts in U-Boot after NXP downstream clk code upstreamed.
I have also tried to converting to use NXP downstream Linux ccf code in u-boot, but there is an issue is some clks are root clks, no parents. However u-boot ccf always requires a parent for a clk. Anyway there is still long time to upstream nxp Linux downstream clk code to Linux.
I would hear your voice about U-Boot part. Proceed with current patch or promoting CCF with NXP downstream clk?
Thanks, Peng.
Update imx8 clock driver to support LPCG and full clocks tree for some modules aligned with kernel.
We classify the clock into serveral types: slice, fixed, lpcg, gpr and mux. Generally slice and fixed clocks are the sources. lpcg, gpr and mux are the downstream of those sources and are used for gating, muxing or dividing functions.
This patch replaces the functions defined in imx8qm and imx8qxp with the clock tables of different clock types. clk-imx8 use unified functions to process these clock tables.
Note: since the clock depends on the power domain of its resource, must power on the resource firstly, then we can get the clock. Otherwise, we can't access lpcg. Thus, the clock dump only works for the slice clock.

Hi Peng,
Hi All,
Subject: [PATCH v2 3/7] clk: imx8: Update imx8 clock driver
Sorry to bring back this topic.
This patch is not converting to CCF following Linux, but it could satisfy u-boot usage and make more feature work.
I checked Linux i.MX8 CCF recently, although Linux upstream has i.MX8 CCF support, but NXP downstream has significantly reimplement the code. So we could not take code directly from Linux upstream, because this would introduce efforts in U-Boot after NXP downstream clk code upstreamed.
I have also tried to converting to use NXP downstream Linux ccf code in u-boot, but there is an issue is some clks are root clks, no parents. However u-boot ccf always requires a parent for a clk. Anyway there is still long time to upstream nxp Linux downstream clk code to Linux.
I would hear your voice about U-Boot part. Proceed with current patch or promoting CCF with NXP downstream clk?
It depends.
One reason for using Linux clocks (backported from Linux) is that there is a chance that this code would be maintained for a long time and hence subsequent updates from Linux would have the chance to work.
With NXP downstream code - it may happen that we will end up with some in-mainline version not being in sync with Linux and with future NXP internal BSP releases.
My standpoint is as follows - if you feel like there is a pretty high chance that NXP downstream clk code will be accepted to Linux _soon_, then I don't mind to have it in U-Boot.
This is all the matter of active maintenance of the CLK code ...
Thanks, Peng.
Update imx8 clock driver to support LPCG and full clocks tree for some modules aligned with kernel.
We classify the clock into serveral types: slice, fixed, lpcg, gpr and mux. Generally slice and fixed clocks are the sources. lpcg, gpr and mux are the downstream of those sources and are used for gating, muxing or dividing functions.
This patch replaces the functions defined in imx8qm and imx8qxp with the clock tables of different clock types. clk-imx8 use unified functions to process these clock tables.
Note: since the clock depends on the power domain of its resource, must power on the resource firstly, then we can get the clock. Otherwise, we can't access lpcg. Thus, the clock dump only works for the slice clock.

Encounter malloc failure in arch_cpu_init_dm when binding "fsl,imx8-mu" node with imx8_scu driver. So increase the early malloc pool to fix the issue.

It seems the feature to support multiple ports should be independent of adding the extra needed clocks. I think they should be two separate patches.
Thanks, -Joe

Make sure that all devices that are powered up by SPL are powered down before entering into the u-boot. Otherwise the subsystem/device will never be powered down by SCFW, due to SPL and u-boot are in different partitions.
Benefiting from power domain driver, this patch implements the function "power_off_pd_devices" to power off all active devices.
