2022-02-25net: ravb: Add tx/rx delay flag checks and support for rgmii-rxidAdam Ford
Some boards like the Beacon RZ/G2 SOM use either flags for tx-internal-delay-ps, rx-internal-delay-ps or rgmii-rxid. In Linux the APSR_RDM flag is set when either rx-internal-delay-ps is set or the mode is rgmii-rxid, and the APSR_TDM is set when tx-internal-delay-ps is found or rgmii-txid is set, and both are set if rgmii-id is set. The ravb driver in U-Boot driver was missing rgmii-rxid support, so add that support in a similar fashion to what is done in Linux. Signed-off-by: Adam Ford <aford173@gmail.com>
2022-02-25clk: ccf: correct the test on the parent uclass in clk_enable/clk_disablePatrick Delaunay
It is safe to check if the uclass id on the device is UCLASS_CLK before to call the clk_ functions, but today this comparison is not done on the device used in API: clkp->dev->parent but on the device himself: clkp->dev. This patch corrects this behavior and tests if the parent device is a clock device before to call the clock API, clk_enable or clk_disable, on this device.

The optional varients of clk_get_* functions are just simple wrappers. Reduce code size a bit by inlining them. On platforms where it is not used (most of them), it will not be compiled in any more.

2022-02-23usb: ehci-omap: Remove OMAP_EHCI_PHYx_RESET_GPIO from KconfigAdam Ford
With the omap-ehci driver now using the phy subsystem to enable and disable reset, the driver no longer needs to know which GPIO's are used, and they can be removed from Kconfig. Signed-off-by: Adam Ford <aford173@gmail.com>
2022-02-23usb: ehci-omap: Use PHY system to manage phy resetsAdam Ford
There are a few boards that use hard-coded GPIO definitions in their respective defconfig files. If the GPIO's are listed in their device trees, the nop-phy can toggle the GPIO's, so the EHCI driver does not need to know anything about the GPIO's. Add functions for getting the phys and remove the GPIO toggles since the phy will now do that. Signed-off-by: Adam Ford <aford173@gmail.com>
2022-02-23usb: ehci-omap: Make Kconfig select PHY if USB_EHCI_OMAPAdam Ford
The USB_EHCI_OMAP driver currently has a series of Kconfig options which let users specify a GPIO for the reset pin. Some devices may have only one reset, while others might have more. Since there is a nop phy driver, let's selct enable the PHY system, and imply the nop phy driver. The nop phy driver can now toggle the reset pins when putting the phy in and out of reset. If the gpio is listed under the phy, it will get toggled and the hard-coded config options specifying the GPIO numbers can eventually go away. Signed-off-by: Adam Ford <aford173@gmail.com>

In commit 3fc92a215b69 ("ddr: marvell: a38x: fix SPLIT_OUT_MIX state decision") I ported a cleaned up and changed version of patch mv_ddr: a380: fix SPLIT_OUT_MIX state decision In the port we removed checking for BYTE_HOMOGENEOUS_SPLIT_OUT bit, because: - the fix seemed to work without it - the bit was checked for only at one place out of two, while the second bit, BYTE_SPLIT_OUT_MIX, was checked for in both cases - without the removal it didn't work on Allied Telesis' x530 board We recently had a chance to test on more boards, and it seems that the change needs to be opposite: instead of removing the check for BYTE_HOMOGENEOUS_SPLIT_OUT from the first if() statement, the check needs to be added also to the second one - it needs to be at both places. With this change all the Turris Omnia boards I have had available to test seem to work, I didn't encounter not even one failed DDR training. As last time, I am noting that I do not understand what this code is actually doing, I haven't studied the DDR training algorithm and I suspect that no one will be able to explain it to U-Boot contributors, so we are left with this blind poking in the code with testing whether it works on several boards and hoping it doesn't break anything for anyone :-(.
