2020-10-08ACPICA: iASL: Return exceptions for string-to-integer conversionsBob Moore
This allows iASL to generate errors by passing exceptions that may be encountered during string-to-integer conversions. The exceptions point out invalid hex, decimal, and octal integers.

2020-10-08ACPICA: Add predefined names found in the SMBus sepcificationBob Moore
Affects run-time (kernel) ACPICA, iASL, and acpi_help. The "SMBus Control Method Interface Specification, Version 1.0, December 10, 1999" containes predefined names: _SBA _SBI _SBR _SBT _SBW. This was done outside of the ACPI specification. This commit adds support for ACPICA to recognize these named objects as predefined named objects.

2020-10-08cpufreq,arm,arm64: restructure definitions of arch_set_freq_scale()Ionela Voinescu
Compared to other arch_* functions, arch_set_freq_scale() has an atypical weak definition that can be replaced by a strong architecture specific implementation. The more typical support for architectural functions involves defining an empty stub in a header file if the symbol is not already defined in architecture code. Some examples involve: - #define arch_scale_freq_capacity topology_get_freq_scale - #define arch_scale_freq_invariant topology_scale_freq_invariant - #define arch_scale_cpu_capacity topology_get_cpu_scale - #define arch_update_cpu_topology topology_update_cpu_topology - #define arch_scale_thermal_pressure topology_get_thermal_pressure - #define arch_set_thermal_pressure topology_set_thermal_pressure Bring arch_set_freq_scale() in line with these functions by renaming it to topology_set_freq_scale() in the arch topology driver, and by defining the arch_set_freq_scale symbol to point to the new function for arm and arm64. While there are other users of the arch_topology driver, this patch defines arch_set_freq_scale for arm and arm64 only, due to their existing definitions of arch_scale_freq_capacity. This is the getter function of the frequency invariance scale factor and without a getter function, the setter function - arch_set_freq_scale() has not purpose.

2020-10-08mwifiex: fix double freeTom Rix
clang static analysis reports this problem: sdio.c:2403:3: warning: Attempt to free released memory kfree(card->mpa_rx.buf); ^~~~~~~~~~~~~~~~~~~~~~~ When mwifiex_init_sdio() fails in its first call to mwifiex_alloc_sdio_mpa_buffer, it falls back to calling it again. If the second alloc of mpa_tx.buf fails, the error handler will try to free the old, previously freed mpa_rx.buf. Reviewing the code, it looks like a second double free would happen with mwifiex_cleanup_sdio(). So set both pointers to NULL when they are freed.

This is partially due to the peripheral clock being disabled when the clock is set. Let's keep the peripheral clock on after probe to fix the problem.

2020-10-08usb: typec: tcpm: Add support for Sink Fast Role SWAP(FRS)Badhri Jagan Sridharan
PD 3.0 spec defines a new mechanism for power role swap called Fast role swap. This change enables TCPM to support FRS when acting as sink. Once the explicit contract is negotiated, sink port is expected to query the source port for sink caps to determine whether the source is FRS capable. Bits 23 & 24 of fixed pdo of the sink caps from the source, when set, indicates the current needed by the source when fast role swap is in progress(Implicit contract phasae). 0 indicates that the source does not support Fast Role Swap. Upon receiving the FRS signal from the source, TCPC(TCPM_FRS_EVENT) informs TCPM to start the Fast role swap sequence. 1. TCPM sends FRS PD message: FR_SWAP_SEND 2. If response is not received within the expiry of SenderResponseTimer, Error recovery is triggered.: FR_SWAP_SEND_TIMEOUT 3. Upon receipt of the accept message, TCPM waits for PSSourceOffTimer for PS_READY message from the partner: FR_SWAP_SNK_SRC_NEW_SINK_READY. TCPC is expected to autonomously turn on vbus once the FRS signal is received and vbus voltage falls below vsafe5v within tSrcFrSwap. This is different from traditional power role swap where the vbus sourcing is turned on by TCPM. 4. By this time, TCPC most likely would have started to source vbus, TCPM waits for tSrcFrSwap to see if the lower level TCPC driver signals TCPM_SOURCING_VBUS event: FR_SWAP_SNK_SRC_SOURCE_VBUS_APPLIED. 5. When TCPC signals sourcing vbus, TCPM sends PS_READY msg and changes the CC pin from Rd to Rp. This is the end of fast role swap sequence and TCPM initiates the sequnce to negotiate explicit contract by transitioning into SRC_STARTUP after SwapSrcStart. The code is written based on the sequence described in "Figure 8-107: Dual-role Port in Sink to Source Fast Role Swap State Diagram" of USB Power Delivery Specification Revision 3.0, Version 1.2.

Chip level TCPC driver for Maxim's TCPCI implementation. This TCPC implementation does not support the following commands: COMMAND.SinkVbus, COMMAND.SourceVbusDefaultVoltage, COMMAND.SourceVbusHighVoltage. Instead the sinking and sourcing from vbus is supported by writes to custom registers.
