2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <[email protected]> Signed-off-by: Tom Rini <[email protected]>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2022-06-06serial: Replace CONFIG_DEBUG_UART_BASE by CONFIG_VAL(DEBUG_UART_BASE)Pali Rohár
CONFIG_VAL(DEBUG_UART_BASE) expands to CONFIG_DEBUG_UART_BASE or CONFIG_SPL_DEBUG_UART_BASE or CONFIG_TPL_DEBUG_UART_BASE and allows boards to set different values for SPL, TPL and U-Boot Proper. For ns16550 driver this support is there since commit d293759d55cc ("serial: ns16550: Add support for SPL_DEBUG_UART_BASE"). Signed-off-by: Pali Rohár <[email protected]>

2021-02-03serial: sifive: Cast dev_read_addr() with uintptr_tBin Meng
dev_read_addr() returns fdt_addr_t which is now a 64-bit address. In a 32-bit build, this causes the following warning seen when building serial_sifive.c: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] Cast the return value with uintptr_t.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass
Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass
Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <[email protected]>

2020-02-05dm: core: Require users of devres to include the headerSimon Glass
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2019-08-15riscv : serial: use rx watermark to indicate rx data is presentSagar Shrikant Kadam
In y-modem transfer mode, tstc/getc fail to check if there is any data available / received in RX FIFO, and so y-modem transfer never succeeds. Using receive watermark bit within ip register fixes the issue.

2019-05-09serial: sifive: Change include orderJagan Teki
Like clk_get_by_index, there is requirement for clk_get_by_index_nodev. In this case to make common code functionalities for dev and nodev, clk_get_by_index is trying to get the index of clock by passing ofnode instead of actual dev like current gpio uclass does. In these scenarios with current order of include files the serial_sifive driver is unable to find CONFIG_ENV_SIZE. In file included from arch/riscv/include/asm/u-boot.h:23:0, from include/dm/of.h:10, from include/dm/ofnode.h:12, from include/clk.h:11, from drivers/serial/serial_sifive.c:6: include/environment.h:145:19: error: 'CONFIG_ENV_SIZE' undeclared here (not in a function); did you mean 'CONFIG_CMD_XIMG'? #define ENV_SIZE (CONFIG_ENV_SIZE - ENV_HEADER_SIZE) So, fix consists of changing the order of include files in serial_sifive.c to include first common.h file.

2019-02-27drivers: serial_sifive: Skip baudrate config if no input clockAtish Patra
It is possible that input clock is not available because clk device was not available and 'clock-frequency' DT property is also not available. In this case, instead of failing we should just skip baudrate config by returning zero.
