2021-06-11arm: mach-k3: j721e_init: Force early probe of clk-k3 driverDave Gerlach
Force the clk-k3 driver to probe early during R5 SPL boot to ensure the default system clock configuration is completed. Many other drivers assume a default state of the clock tree and it is currently possible for them to probe before clk-k3 depending on the exact system configuration.

2021-06-11cmd: ti: pd: Add debug command for K3 power domainsTero Kristo
Add support command for debugging K3 power domains. This is useful with the HSM rearch setup, where power domains are directly controlled by SPL instead of going through the TI SCI layer. The debugging support is only available in the u-boot codebase though, so the raw register access power domain layer must be enabled on u-boot side for this to work. By default, u-boot side uses the TI SCI layer, and R5 SPL only uses the direct access methods.

2021-06-08Merge branch '2021-06-08-display-and-logging-updates' into nextTom Rini
To quote Simon, first for the display changes: At present we have two ways of showing a hex dump. Once has been in U-Boot since the dawn of time and the other was recently added from Linux. They both have their own unique features. This series makes a few changes to bring them closer together. It also adds support for logging a buffer, which is useful since it can put it through the same log drivers as other logging output. Also it adds tests, so we can check the behaviour. And then the logging changes: At present when logging is not enabled, all log() calls become nops. This does not seem right, since if the log level is high enough then there should be some sort of message. So in that case, this series updates it to print the message if the log level is above LOGL_INFO. This mimics the behaviour for the log_...() macros like log_debug() and log_info(), so we can drop the special case for these. Also the current implementation does not support multiple log calls on the same line nicely. The tags are repeated so the line is very hard to read. This series adds that as a new feature.
2021-06-08log: Convert log values to printf() if not enabledSimon Glass
At present if logging not enabled, log_info() becomes a nop. But we want log output at the 'info' level to be akin to printf(). Update the macro to pass the output straight to printf() in this case. This mimics the behaviour for the log_...() macros like log_debug() and log_info(), so we can drop the special case for these. Add new tests to cover this case.
