2021-03-24binder: BINDER_FREEZE ioctlMarco Ballesio
Frozen tasks can't process binder transactions, so a way is required to inform transmitting ends of communication failures due to the frozen state of their receiving counterparts. Additionally, races are possible between transitions to frozen state and binder transactions enqueued to a specific process. Implement BINDER_FREEZE ioctl for user space to inform the binder driver about the intention to freeze or unfreeze a process. When the ioctl is called, block the caller until any pending binder transactions toward the target process are flushed. Return an error to transactions to processes marked as frozen.

2021-03-24misc: lis3lv02d: Fix false-positive WARN on various HP modelsHans de Goede
Before this commit lis3lv02d_get_pwron_wait() had a WARN_ONCE() to catch a potential divide by 0. WARN macros should only be used to catch internal kernel bugs and that is not the case here. We have been receiving a lot of bug reports about kernel backtraces caused by this WARN. The div value being checked comes from the lis3->odrs[] array. Which is sized to be a power-of-2 matching the number of bits in lis3->odr_mask. The only lis3 model where this array is not entirely filled with non zero values. IOW the only model where we can hit the div == 0 check is the 3dc ("8 bits 3DC sensor") model: int lis3_3dc_rates[16] = {0, 1, 10, 25, 50, 100, 200, 400, 1600, 5000}; Note the 0 value at index 0, according to the datasheet an odr index of 0 means "Power-down mode". HP typically uses a lis3 accelerometer for HDD fall protection. What I believe is happening here is that on newer HP devices, which only contain a SDD, the BIOS is leaving the lis3 device powered-down since it is not used for HDD fall protection. Note that the lis3_3dc_rates array initializer only specifies 10 values, which matches the datasheet. So it also contains 6 zero values at the end. Replace the WARN with a normal check, which treats an odr index of 0 as power-down and uses a normal dev_err() to report the error in case odr index point past the initialized part of the array.

This patch adds support for Xilinx Dynamic Function eXchange(DFX) AXI shutdown manager IP. It can be used to safely handling the AXI traffic on a Reconfigurable Partition when it is undergoing dynamic reconfiguration and there by preventing system deadlock that may occur if AXI transactions are interrupted during reconfiguration. PR-Decoupler and AXI shutdown manager are completely different IPs. But both the IP registers are compatible and also both belong to the same sub-system (fpga-bridge).So using same driver for both IP's.
