2020-12-10can: m_can: add PCI glue driver for Intel Elkhart LakeJarkko Nikula
Add support for M_CAN controller on Intel Elkhart Lake attached to the PCI bus. It integrates the Bosch M_CAN controller with Message RAM and the wrapper IP block with additional registers which all of them are within the same MMIO range. Currently only interrupt control register from wrapper IP is used and the MRAM configuration is expected to come from the firmware via "bosch,mram-cfg" device property and parsed by m_can.c core. Initial implementation is done by Felipe Balbi while he was working at Intel with later changes from Raymond Tan and me.

2020-12-10can: m_can: move runtime PM enable/disable to m_can_platformPatrik Flykt
This is a preparatory patch for upcoming PCI based M_CAN devices. The current PM implementation would cause PCI based drivers to enable PM twice, once when the PCI device is added and a second time in m_can_class_register(). This will cause 'Unbalanced pm_runtime_enable!' to be logged, and is a situation that should be avoided. Therefore, in anticipation of PCI devices, move PM enabling out from M_CAN class registration to its only user, the m_can_platform driver.

2020-12-10can: isotp: add SF_BROADCAST support for functional addressingOliver Hartkopp
When CAN_ISOTP_SF_BROADCAST is set in the CAN_ISOTP_OPTS flags the CAN_ISOTP socket is switched into functional addressing mode, where only single frame (SF) protocol data units can be send on the specified CAN interface and the given tp.tx_id after bind(). In opposite to normal and extended addressing this socket does not register a CAN-ID for reception which would be needed for a 1-to-1 ISOTP connection with a segmented bi-directional data transfer. Sending SFs on this socket is therefore a TX-only 'broadcast' operation.

2020-12-10zonefs: fix page reference and BIO leakDamien Le Moal
In zonefs_file_dio_append(), the pages obtained using bio_iov_iter_get_pages() are not released on completion of the REQ_OP_APPEND BIO, nor when bio_iov_iter_get_pages() fails. Furthermore, a call to bio_put() is missing when bio_iov_iter_get_pages() fails. Fix these resource leaks by adding BIO resource release code (bio_put()i and bio_release_pages()) at the end of the function after the BIO execution and add a jump to this resource cleanup code in case of bio_iov_iter_get_pages() failure. While at it, also fix the call to task_io_account_write() to be passed the correct BIO size instead of bio_iov_iter_get_pages() return value.

2020-12-09net: hns3: adjust rss tc mode configure commandGuojia Liao
For the max rss size of PF may be up to 512, the max queue number of single tc may be up to 512 too. For the total queue numbers may be up to 1280, so the queue offset of each tc may be more than 1024. So adjust the rss tc mode configuration command, including extend tc size field from 10 bits to 11 bits, and extend tc size field from 3 bits to 4 bits.

2020-12-09net: hns3: adjust rss indirection table configure commandGuojia Liao
For the max rss size of PF may be up to 512, so adjust the command of configuring rss indirection table to support queue id larger than 255. The width of queue id is extended from 8 bits to 10 bits. The high 2 bits are stored in filed rss_qid_h when the queue id is larger than 255.

2020-12-09net: hns3: add support for max 512 rss sizeGuojia Liao
Currently, the driver gets the max rss size from configuration file when initialization. Both the PF and VF share the same max rss size, and no more than 128. For DEVICE_VERSION_V3, the max rss size for PF can be up to 512, so there is a new field in configuration file to store it, the old filed is used for VF. To be compatible with boards using old configure file, the PF will use the old filed if the one is zero. For the rss size may be larger than 256, so the type of rss_indirection_tbl of struct hclge_vport should be changed to u16 as well.

Some new device supports forwarding packet to queues of specified TC when flow director rule hit. So add support to configure flow director rule by tc flower. To avoid rule conflict, add a new flow director mode HCLGE_FD_TC_FLOWER_ACTIVE, and only one mode can be active at the same time.

2020-12-09net: hns3: add support for tc mqprio offloadJian Shen
Currently, the HNS3 driver only supports offload for tc number and prio_tc. This patch adds support for other qopts, including queues count and offset for each tc. When enable tc mqprio offload, it's not allowed to change queue numbers by ethtool. For hardware limitation, the queue number of each tc should be power of 2. For the queues is not assigned to each tc by average, so it's should return vport->alloc_tqps for hclge_get_max_channels().

2020-12-09Input: tm2-touchkey - add vddio regulatorStephan Gerhold
The Samsung touchkey controllers are often used with external pull-up for the interrupt line and the I2C lines, so we might need to enable a regulator to bring the lines into usable state. Otherwise, this might cause spurious interrupts and reading from I2C will fail. Implement support for a "vddio-supply" that is enabled by the tm2-touchkey driver so that the regulator gets enabled when needed.
