rockchip: Fix incorrect constant name in RAM init code

2023-04-02T16:57:12+00:00

A condition in the rk3399 RAM initialization code used the old
CONFIG_RAM_RK3399_LPDDR4 constant name. This commit changes the
condition to use the correct CONFIG_RAM_ROCKCHIP_LPDDR4 constant.

mmc: bcm2835-host: let firmware manage the clock divisor

2023-03-24T14:43:20+00:00

Newer firmware can manage the SDCDIV clock divisor register, allowing
the divisor to scale with the core as necessary.

Leverage this ability if the firmware supports it.

Adapted from the following raspberrypi Linux kernel commit:

dma: ti: k3-udma: Fix channel hang on teardown

2023-03-22T16:51:15+00:00

Setting RX flow error handling will stall the channel until descriptors
are available to move RX data. Setting this bit causes issues when
tearing down ethernet DMA channel at the end of TFTP transfer as
unrelated network packets can cause teardown to stall indefinitely waiting
for driver to queue add more desc leading to channel hang with error
logs:
udma_stop_dev2mem TIMEOUT !
udma_stop_dev2mem: peer not stopped TIMEOUT !
udma_stop_dev2mem TIMEOUT !

Fix this by clearing rx_error_handling similar to how its done for UDMA
as part of udma_alloc_rchan_sci_req()

This fixes occasional TFTP Failures seen when downloading multiple files
one after the other on AM64/AM62 SoCs.

clk: renesas: Pack reset identifier before look up

2023-03-20T01:46:44+00:00

The reset identifier must be processed via MOD_CLK_PACK() before it is
used to look up register and bit within reset_regs or reset_clear_regs
arrays, otherwise completely bogus register and bit is picked from the
arrays, one which may even be out of range.
