* ipq806x: remove support for kernel 4.19Adrian Schmutzler2020-10-1956-8749/+0
| | | | | | | | | | | | | The target uses 5.4 as default kernel since 04/2020. Kernel 4.19 support is not really maintained anymore, and there has been a lot of changes between 4.19 and 5.4 on this target. Despite, new devices are typically added for 5.4 only anyway. Thus, make maintaining of old stuff and reviewing of new stuff easier by removing support for kernel 4.19. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* ipq806x: opp/core: fix broken patch Handle opp voltage adjustAnsuel Smith2020-01-082-11/+4
| | | | | | | | | | The opp_notifier introduced with patch 0054-Handle-OPP-voltage adjust for some reason missed the actual registration in the opp struct, resulting in never being registred. This was present in kernel 4.9 patchset but dropped in the transition to 4.14. Reintroduce this and fix patch 0055 about L2 cache scaling. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>

* ipq806x: rework ipq806x specific tsense temp driverAnsuel Smith2019-12-261-0/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | Tsense driver for ipq806x have various problem. - Emit wrong error. On probing of this driver, nvmem driver can be not ready and this cause a EDEFER error. Actually this is not an error as the kernel will retry to probe the driver after the nvmem driver is loaded. - Use uninitialized value on trigger of critical temp - Doesn't free allocated memory Because of this, rework the driver and improve it by removing extra load of data. Change the logic of loading data. Use the backup calib data only when the calib data is not present. As the calibration is only needed to set the temp offset, we don't really need to read both calib data and set the offset based only on the backup one. Also change how the notifier function work. At times when we output the trigger message, we already have read the temp so remove the extra read and the wrong uninitialized data that probably caused a kernel panic for null pointer exception. (Think we never experience this bug because the router never reached that temp ever... So just lucky) Tested-by: Stefan Lippers-Hollmann <s.l-h@gmx.de> [nbg6817/ipq8065] Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>

* ipq806x: fix bug in L2 cache scalingAnsuel Smith2019-12-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been notice a buf in L2 cache scaling where the scaling is not done proprely if the frequency is set to the initial state before the new frequency. From: https://patchwork.kernel.org/patch/10565443/ * The clocks are set to aux clock rate first to make sure the * secondary mux is not sourcing off of QSB. The rate is then set to * two different rates to force a HFPLL reinit under all * circumstances. In the initial stage of boot to force a new frequency to apply, is needed to first set the frequency back to the lowest one (aux_rate) and then to the target one. This force and make sure the controller actually switch the frequency to the right one. Apply the same mechanism to L2 frequency scaling. Before scaling to the target frequency, first set the frequency to the aux_rate to force the transition, then scale it to the target frequency. Doing the wrong way can produce unexpected results and could lock the scaling mechanism until a full reboot is done (Causing a full reset by the krait-cc driver) From: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=77612720a2362230af726baa4149c40ec7a7fb05 When the Hfplls are reprogrammed during the rate change, the primary muxes which are sourced from the same hfpll for higher frequencies, needs to be switched to the 'safe secondary mux' as the parent for that small window. This is done by registering a clk notifier for the muxes and switching to the safe parent in the PRE_RATE_CHANGE notifier and back to the original parent in the POST_RATE_CHANGE notifier. This should apply also to L2 scaling... as we can't relly use the notifier, we manually do this on L2 scaling.

* ipq806x: fix tsens driver in 4.19Ansuel Smith2019-12-191-0/+20
| | | | | | | | | | | | | | | | | | | Added patch: - 063-3 Fix tsense shared memory problem Recent changes in ioremap_resource function are causing fails for the memory areas which are already mapped. This changes are causing tsense driver failures during initialization: qcom-tsens 900000.thermal-sensor: tsens init failed So this patch uses simple ioremap in order to use this shared memory space.
