https://gitlab.denx.de/u-boot/custodians/u-boot-clk - Add CCF clocks definitions for iMX6Q enet (ETH) - Several fixes for CCF framework - the most notable is the one, which adds get_rate helper to clk-mux.c - Improvements for clk command - better visibility and alignment.
2020-08-24clk: ccf: Add missing #include <dm/uclass.h> to clk-mux.cLukasz Majewski
After adding custom get_rate helper function it was necessary to include <dm/uclass.h> to avoid warnings about missing uclass_get_device_by_name. Signed-off-by: Lukasz Majewski <lukma@denx.de> Series-to: u-boot
2020-08-24clk: ccf: mux: change the get_rate helperDario Binacchi
The previous version of the get_rate helper does not work if the mux clock parent is changed after the probe. This error has not been detected because this condition has not been tested. The error occurs because the set_parent helper does not change the parent of the clock device but only the clock selection register. Since changing the parent of a probed device can be tricky, the new version of the get_rate helper provides the rate of the selected clock and not that of the parent.

2020-08-24clk: ccf: mux: fix access to the sandbox registerDario Binacchi
The tests developed for the mux clock are run on the sandbox. They don't call the clk_mux_set_parent routine and therefore they do not detect this error. Signed-off-by: Dario Binacchi <dariobin@libero.it>

2020-08-24clk: set flags in the ccf registration routinesDario Binacchi
The top-level framework flags are passed as parameter to the common clock framework (ccf) registration routines without being used. Checks of the flags setting added by the patch have been added in the ccf test. Signed-off-by: Dario Binacchi <dariobin@libero.it>
2020-08-24dm: test: clk: add the test for the ccf gated clockDario Binacchi
Unlike the other clock types, in the case of the gated clock, a new driver has been developed which does not use the registering routine provided by the common clock framework. The addition of the ecspi0 clock to sandbox therefore allows testing the ccf gate clock. Signed-off-by: Dario Binacchi <dariobin@libero.it> Reviewed-by: Simon Glass <sjg@chromium.org>
2020-08-24clk: imx6: Add definition for IMX6QDL_CLK_ENET_REF clockLukasz Majewski
After commit 673f6597321d ("net: fec_mxc: support i.MX8M with CLK_CCF") all NXP boards, which are not IMX8 and in the same time are supporting CCF need to provide PTP clock. On the i.MX6Q this clock is provided with IMX6QDL_CLK_ENET_REF in the Linux kernel's CCF. Code in this change models the simplest case when enet reference clock is generated from 'osc' clock.

When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To help this tedious work, this commit converts devfdt_get_addr_ptr() to dev_read_addr_ptr() by coccinelle. I also removed redundant casts because dev_read_addr_ptr() returns an opaque pointer.

According to the description of devfdt_get_addr_ptr, this function should return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE. Fix this by making devfdt_get_addr_ptr return NULL on failure, as described in the function comments. Also, update the drivers currently checking (void *)FDT_ADDR_T_NONE to check for NULL.

2020-08-04sifive: reset: add DM based reset driver for SiFive SoC'sSagar Shrikant Kadam
PRCI module within SiFive SoC's has register with which we can reset the sub-systems within the SoC. The resets to DDR and ethernet sub systems within FU540-C000 SoC are active low, and are hold low by default on power-up. Currently these are directly asserted within prci driver via register read/write. With the DM based reset driver support here, we bind the reset driver with clock (prci) driver and assert the reset signals of both sub-system's appropriately.

2020-07-09dtoc: extend dtoc to use struct driver_info when linking nodesWalter Lozano
In the current implementation, when dtoc parses a dtb to generate a struct platdata it converts the information related to linked nodes as pointers to struct platdata of destination nodes. By doing this, it makes difficult to get pointer to udevices created based on these information. This patch extends dtoc to use struct driver_info when populating information about linked nodes, which makes it easier to later get the devices created. In this context, reimplement functions like clk_get_by_index_platdata() which made use of the previous approach.

2020-07-09core: add support for U_BOOT_DRIVER_ALIASWalter Lozano
Currently when using OF_PLATDATA the binding between devices and drivers is done trying to match the compatible string in the node with a driver name. However, usually a single driver supports multiple compatible strings which causes that only devices which its compatible string matches a driver name get bound. To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro, which generates no code at all, but allows an easy way to declare driver name aliases. Thanks to this, dtoc could be improve to look for the driver name based on its alias when it populates the U_BOOT_DEVICE entry.

2020-07-09drivers: rename drivers to match compatible stringWalter Lozano
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.
