[ Upstream commit bc288a9278 ]
The probe function calls dispc_softreset() before runtime PM is enabled
and without enabling any of the DSS clocks. This happens to work by
luck, and we need to make sure the DSS HW is active and the fclk is
enabled.
To fix the above, add a new function, dispc_init_hw(), which does:
- pm_runtime_set_active()
- clk_prepare_enable(fclk)
- dispc_softreset().
This ensures that the reset can be successfully accomplished.
Note that we use pm_runtime_set_active(), not the normal
pm_runtime_get(). The reason for this is that at this point we haven't
enabled the runtime PM yet and also we don't want the normal resume
callback to be called: the dispc resume callback does some initial HW
setup, and it expects that the HW was off (no video ports are
streaming). If the bootloader has enabled the DSS and has set up a
boot time splash-screen, the DSS would be enabled and streaming which
might lead to issues with the normal resume callback.

The patch 1da177e4c3: "Linux-2.6.12-rc2" from Apr 16, 2005

641 ret = mthca_cmd_imm(dev, 0, &out, 0, 0, CMD_SYS_EN, CMD_TIME_CLASS_D);

[ Upstream commit 22aa1a2090 ]
The layout of the registers {TILER,SHADER,L2}_PWROFF_LO, used to request
powering off cores, is the same as the {TILER,SHADER,L2}_PWRON_LO ones:
this means that in order to request poweroff of cores, we are supposed
to write a bitmask of cores that should be powered off!
This means that the panfrost_gpu_power_off() function has always been
doing nothing.
Fix powering off the GPU by writing a bitmask of the cores to poweroff
to the relevant PWROFF_LO registers and then check that the transition
(from ON to OFF) has finished by polling the relevant PWRTRANS_LO
registers.
While at it, in order to avoid code duplication, move the core mask
logic from panfrost_gpu_power_on() to a new panfrost_get_core_mask()
function, used in both poweron and poweroff.

[ Upstream commit 7707dd6022 ]
The current code does '(bpp << 4) / 16' in the MST PBN
calculation, but that is just the same as 'bpp' so the
DSC codepath achieves absolutely nothing. Fix it up so that
the fractional part of the bpp value is actually used instead
of truncated away. 64*1006 has enough zero lsbs that we can
just shift that down in the dividend and thus still manage
to stick to a 32bit divisor.
And while touching this, let's just make the whole thing more
straightforward by making the passed in bpp value .4 binary
fixed point always, instead of having to pass in different
things based on whether DSC is enabled or not.

- Fix DSC kunit test cases.

At the moment, the GigE port is enabled in the mlxbf_gige_probe
function. If the mlxbf_gige_open is not executed, this could cause
pause frames to increase in the case where there is high backgroud
traffic. This results in clogging the port.
So move enabling the OOB port to mlxbf_gige_open.

[ Upstream commit ef210ef85d ]
Although the link is up, there is no ip assigned on setups with high background
traffic. Nothing is transmitted nor received. The RX error count keeps on
increasing. After several minutes, the RX error count stagnates and the
GigE interface finally gets an ip.
The issue is that mlxbf_gige_rx_init() is called before phy_start().
As soon as the RX DMA is enabled in mlxbf_gige_rx_init(), the RX CI reaches the max
of 128, and becomes equal to RX PI. RX CI doesn't decrease since the code hasn't
ran phy_start yet.
Bring the PHY up before starting the RX.
