2025-04-23rockchip: otp: Add support for RK3576Heiko Stuebner
Add support for RK3576 compatible. The RK3576 OTP uses the same read mechanism as the RK3588, just with different values for offset and size. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
2025-04-23rockchip: otp: Add support for RK3528Jonas Karlman
Add support for the OTP controller in RK3528. The OTPC is similar to the OTPC in RK3568 and can use the same ops for reading OTP data. Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2023-11-10rockchip: otp: Add support for RV1126Tim Lunn
Extend the otp driver to read rv1126 otp. This driver code was adapted from the Rockchip BSP stack. Signed-off-by: Tim Lunn <tim@feathertop.org> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
2023-04-21rockchip: otp: fix misc_read() return valuesJohn Keeping
The documentation for misc_read() says: Return: number of bytes read if OK (may be 0 if EOF), -ve on error The Rockchip efuse driver implements this so it should return the number of bytes read rather than zero on success. Fix this so that the driver follows the usual contract for read operations.

2023-02-28rockchip: otp: Refactor to use driver data and opsJonas Karlman
Refactor the driver to use driver data and ops to simplify handling of SoCs that require a unique read op. Use readl_poll_sleep_timeout instead of a custom poll loop, and add validation of input parameter to main read op.

2020-12-13dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass
Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass
Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

Newer Rockchip socs like the px30 use a different ip block to handle one-time-programmable memory, so add a misc driver for it as well.
