2020-07-17x86: apl: Fix save/restore of ITSS prioritiesSimon Glass
The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error.

2020-07-09dtoc: extend dtoc to use struct driver_info when linking nodesWalter Lozano
In the current implementation, when dtoc parses a dtb to generate a struct platdata it converts the information related to linked nodes as pointers to struct platdata of destination nodes. By doing this, it makes difficult to get pointer to udevices created based on these information. This patch extends dtoc to use struct driver_info when populating information about linked nodes, which makes it easier to later get the devices created. In this context, reimplement functions like clk_get_by_index_platdata() which made use of the previous approach.

2020-07-09drivers: rename drivers to match compatible stringWalter Lozano
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

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.

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.
