| * | bus: arm-integrator-lm: Fix return value check in integrator_ap_lm_probe() | Wei Yongjun | 2020-05-26 | 1 | -2/+2 |
| | | | | | | | | | | | | | | | In case of error, the function of_find_matching_node() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

| * | bus: Add driver for Integrator/AP logic modules | Linus Walleij | 2020-04-28 | 1 | -0/+128 |
| The logic modules on the Integrator/AP (Application Platform) are logic tiles with (typically) one or a few peripheral devices. They are most commonly used for FPGA prototyping. Using the device tree node for logic tiles, we probe them in order and check if the special system controller register confirm their presence before populating the node for a tile. This supercedes the code in arch/arm/mach-integrator/lm.[c|h] and makes it possible to populate the tiles using the device tree instead of boardfile-based descriptions. Tested with all peripherals including graphics and MMC card working fine with the IM-PD1 example tile from Arm. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> | |||||
