simply returns a set of configs saved from a previous invocation of

in from the pinconf core, which does not match the current hardware

current pin config state of the only pin in the group.

Any registered clk_core structure can have a NULL pointer in its dev
field. While never actually documented, this is evidenced by the wide
usage of clk_register and clk_hw_register with a NULL device pointer,
and the fact that the core of_clk_hw_register() function also passes a
NULL device pointer.
A call to clk_hw_get_clk() on a clk_hw struct whose clk_core is in that
case will result in a NULL pointer derefence when it calls dev_name() on
that NULL device pointer.
Add a test for this case and use NULL as the dev_id if the device
pointer is NULL.

Set em485->active_timer = NULL isn't always enough to take out the stop
timer. While there is a check that it acts in the right state (i.e.
waiting for RTS-after-send to pass after sending some chars) but the
following might happen:
- CPU1: some chars send, shifter becomes empty, stop tx timer armed
- CPU0: more chars send before RTS-after-send expired
- CPU0: shifter empty irq, port lock taken
- CPU1: tx timer triggers, waits for port lock
- CPU0: em485->active_timer = &em485->stop_tx_timer, hrtimer_start(),
releases lock()
- CPU1: get lock, see em485->active_timer == &em485->stop_tx_timer,
tear down RTS too early
This fix bases on research done by Steffen Trumtrar.

[ Upstream commit 32942d33d6 ]
Just like every other family BCM4908 should get its own enum value. That
is required to properly handle it in chipset conditional code.
The real change is excluding BCM4908 from the PLL reprogramming code
(see brcmusb_usb3_pll_54mhz()). I'm not sure what's the BCM4908
reference clock frequency but:
1. BCM4908 custom driver from Broadcom's SDK doesn't reprogram PLL
2. Doing that in Linux driver stopped PHY handling some USB 3.0 devices
This change makes USB 3.0 PHY recognize e.g.:
1. 04e8:6860 - Samsung Electronics Co., Ltd Galaxy series, misc. (MTP mode)
2. 1058:259f - Western Digital My Passport 259F
Broadcom's STB SoCs come with a set of SUN_TOP_CTRL_* registers that
allow reading chip family and product ids. Such a block & register is
missing on BCM4908 so this commit introduces "compatible" string
specific binding.

[ Upstream commit 3153fa38e3 ]
According to the comment of the function phy_mipi_dphy_get_default_config(),
it uses minimum D-PHY timings based on MIPI D-PHY specification. They are
derived from the valid ranges specified in Section 6.9, Table 14, Page 41
of the D-PHY specification (v1.2). The table 14 explicitly mentions that
the minimum T-LPX parameter is 50 nanoseconds and the minimum TA-SURE
parameter is T-LPX nanoseconds. Likewise, the kernel doc of the 'lpx' and
'ta_sure' members of struct phy_configure_opts_mipi_dphy mentions that
the minimum values are 50000 picoseconds and @lpx picoseconds respectively.
Also, the function phy_mipi_dphy_config_validate() checks if cfg->lpx is
less than 50000 picoseconds and if cfg->ta_sure is less than cfg->lpx,
which hints the same minimum values.
Without this patch, the function phy_mipi_dphy_get_default_config()
wrongly sets cfg->lpx to 60000 picoseconds and cfg->ta_sure to 2 * cfg->lpx.
So, let's correct them to 50000 picoseconds and cfg->lpx respectively.
Note that I've only tested the patch with RM67191 DSI panel on i.MX8mq EVK.
Help is needed to test with other i.MX8mq, Meson and Rockchip platforms,
as I don't have the hardwares.

[ Upstream commit b77d8306d8 ]
Use floor ops on SDCC1 APPS clock in order to round down selected clock
frequency and avoid overclocking SD/eMMC cards.
For example, currently HS200 cards were failling tuning as they were
actually being clocked at 384MHz instead of 192MHz.
This caused some boards to disable 1.8V I/O and force the eMMC into the
standard HS mode (50MHz) and that appeared to work despite the eMMC being
overclocked to 96Mhz in that case.
There was a previous commit to use floor ops on SDCC clocks, but it looks
to have only covered SDCC2 clock.

[ Upstream commit a603ca60ce ]
Commit 54da3e381c ("serial: 8250_aspeed_vuart: use UPF_IOREMAP to
set up register mapping") fixed a bug that had, as a side-effect,
prevented the 8250_aspeed_vuart driver from enabling the VUART's
FIFOs. However, fixing that (and hence enabling the FIFOs) has in
turn revealed what appears to be a hardware bug in the ASPEED VUART in
which the host-side THRE bit doesn't get if the BMC-side receive FIFO
trigger level is set to anything but one byte. This causes problems
for polled-mode writes from the host -- for example, Linux kernel
console writes proceed at a glacial pace (less than 100 bytes per
second) because the write path waits for a 10ms timeout to expire
after every character instead of being able to continue on to the next
character upon seeing THRE asserted. (GRUB behaves similarly.)
As a workaround, introduce a new port type for the ASPEED VUART that's
identical to PORT_16550A as it had previously been using, but with
UART_FCR_R_TRIG_00 instead to set the receive FIFO trigger level to
one byte, which (experimentally) seems to avoid the problematic THRE
behavior.
