2020-05-28misc: i2c_eeprom: implement different probe test eeprom offsetEugen Hristev
Because of this commit : 5ae84860b0 ("misc: i2c_eeprom: verify that the chip is functional at probe()") at probe time, each eeprom is tested for read at offset 0. The Atmel AT24MAC402 eeprom has different mapping. One i2c slave address is used for the lower 0x80 bytes and another i2c slave address is used for the upper 0x80 bytes. Because of this basically the i2c master sees 2 different slaves. We need the upper bytes because we read the unique MAC address from this EEPROM area. However this implies that our slave address will return error on reads from address 0x0 to 0x80. To solve this, implemented an offset field inside platform data that is by default 0 (as it is used now), but can be changed in the compatible table. The probe function will now read at this offset and use it, instead of blindly checking offset 0. This will fix the regression noticed on these EEPROMs since the commit abovementioned that introduces the probe failed issue.

We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them.

2020-03-03misc: pmic_esm: Add support for PMIC ESM driverTero Kristo
The ESM (Error Signal Monitor) is used on certain PMIC versions to handle error signals propagating from rest of the system. If these reach the PMIC, it is typically a last resort fatal error which requires a system reset. The ESM driver does the proper configuration for the ESM module to reach this end goal. Initially, only TPS65941 PMIC is supported for this. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2020-03-03misc: k3_esm: Add support for Texas Instruments K3 ESM driverTero Kristo
The ESM (Error Signaling Module) is used to route error signals within the K3 SoCs somewhat similar to interrupts.

The u-boot level ESM driver is just used to configure the ESM signals so that they get routed to proper destination. Signed-off-by: Tero Kristo <t-kristo@ti.com>

2020-02-07dm: irq: Add support for requesting interruptsSimon Glass
At present driver model supports the IRQ uclass but there is no way to request a particular interrupt for a driver. Add a mechanism, similar to clock and reset, to read the interrupts required by a device from the device tree and to request those interrupts. U-Boot itself does not have interrupt-driven handlers, so just provide a means to read and clear an interrupt. This can be useful to handle peripherals which must use an interrupt to determine when data is available, for example. Bring over the basic binding file as well, from Linux v5.4. Note that the older binding is not supported in U-Boot; the newer 'special form' must be used. Add a simple test of the new functionality.

2020-02-07dm: irq: Add support for interrupt controller typesSimon Glass
There can be different types of interrupt controllers in a system and some drivers may need to distinguish between these. In general this can be handled using the device tree by adding the interrupt information to device nodes. However on x86 devices we have interrupt controllers which are not tied to any particular device and not really used in U-Boot. These still need to be inited, so a convenient method is to give each controller a type and allow a particular controller type to be probed. Add support for this in sandbox along with a test.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-02-05dm: core: Require users of devres to include the headerSimon Glass
