bcm2835-sdhost: Workaround for "slow" sectors Some cards have been seen to cause timeouts after certain sectors are read. This workaround enforces a minimum delay between the stop after reading one of those sectors and a subsequent data command. Using CMD23 (SET_BLOCK_COUNT) avoids this problem, so good cards will not be penalised by this workaround. Signed-off-by: Phil Elwell <phil@raspberrypi.org>

serial: Take care starting a hung-up tty's port tty_port_hangup sets a port's tty field to NULL (holding the port lock), but uart_tx_stopped, called from __uart_start (with the port lock), uses the tty field without checking for NULL. Change uart_tx_stopped to treat a NULL tty field as another stopped indication. Signed-off-by: Phil Elwell <phil@raspberrypi.org>

pinctrl-bcm2835: Fix cut-and-paste error in "pull" parsing The DT bindings for pinctrl-bcm2835 allow both the function and pull to contain either one entry or one per pin. However, an error in the DT parsing can cause failures if the number of pulls differs from the number of functions.
