regmap: Add bulk read/write callbacks into regmap_config

2024-03-15T14:48:23+00:00

[ Upstream commit d77e745613680c54708470402e2b623dcd769681 ] Currently the regmap_config structure only allows the user to implement single element register read/write using .reg_read/.reg_write callbacks. The regmap_bus already implements bulk counterparts of both, and is being misused as a workaround for the missing bulk read/write callbacks in regmap_config by a couple of drivers. To stop this misuse, add the bulk read/write callbacks to regmap_config and call them from the regmap core code.

regmap: allow to define reg_update_bits for no bus configuration

2024-03-15T14:48:22+00:00

[ Upstream commit 02d6fdecb9c38de19065f6bed8d5214556fd061d ] Some device requires a special handling for reg_update_bits and can't use the normal regmap read write logic. An example is when locking is handled by the device and rmw operations requires to do atomic operations. Allow to declare a dedicated function in regmap_config for reg_update_bits in no bus configuration.

regmap: irq: Add support to clear ack registers

2020-10-05T17:35:30+00:00

For particular codec HWs have requirement to toggle interrupt clear register twice 0->1->0. To accommodate it, need to add one more field (clear_ack) in the regmap_irq struct and update regmap-irq driver to support it.

Merge tag 'regmap-field-bulk-api' into regmap-5.10

regmap: Add a bulk field API Useful for devices with many fields.

regmap: add support to regmap_field_bulk_alloc/free apis

2020-09-28T19:50:03+00:00

Usage of regmap_field_alloc becomes much overhead when number of fields exceed more than 3. QCOM LPASS driver has extensively converted to use regmap_fields. Using new bulk api to allocate fields makes it much more cleaner code to read!

regmap: Add can_sleep configuration option

2020-09-02T18:53:27+00:00

Regmap can't sleep if spinlock is used for the locking protection. This patch fixes regression caused by a previous commit that switched regmap to use fsleep() and this broke Amlogic S922X platform. This patch adds new configuration option for regmap users, allowing to specify whether regmap operations can sleep and assuming that sleep is allowed if mutex is used for the regmap locking protection.

regmap: add Intel SPI Slave to AVMM Bus Bridge support

2020-08-26T18:46:38+00:00

This patch add support for regmap APIs that are intended to be used by the drivers of some SPI slave chips which integrate the "SPI slave to Avalon Master Bridge" (spi-avmm) IP. The spi-avmm IP acts as a bridge to convert encoded streams of bytes from the host to the chip's internal register read/write on Avalon bus. The driver implements the register read/write operations for a generic SPI master to access the sub devices behind spi-avmm bridge.
