From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michal Simek Date: Wed, 24 Apr 2013 10:27:50 +0200 Subject: [U-Boot] [RFC PATCH 0/1] GPIO support for Microblaze Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de I want to also write gpio support for Zynq and this driver should be also used for arm zynq. Currently we have support just for only gpio controller but not for various of them. That's why I would like to get some input from you if possible to add dynamic gpio allocation which could be also helpful for OF support. Output from my gpio status on Microblaze is below. Thanks, Michal U-Boot> gpio status gpio_info: reset/40000000 (0-0) GPIO_0: reset_pin is an INPUT value = 0 gpio_info: led/40040000 (1-5) GPIO_1: UNKNOWN is an INPUT value = 0 GPIO_2: UNKNOWN is an OUTPUT value = 1 GPIO_3: UNKNOWN is an INPUT value = 0 GPIO_4: UNKNOWN is an INPUT value = 0 GPIO_5: UNKNOWN is an OUTPUT value = 0 Michal Simek (1): gpio: Add support for microblaze xilinx GPIO arch/microblaze/include/asm/gpio.h | 50 +--- .../xilinx/microblaze-generic/microblaze-generic.c | 17 +- drivers/gpio/Makefile | 1 + drivers/gpio/xilinx_gpio.c | 323 +++++++++++++++++++++ include/configs/microblaze-generic.h | 3 +- 5 files changed, 353 insertions(+), 41 deletions(-) create mode 100644 drivers/gpio/xilinx_gpio.c -- 1.8.2.1 -------------- next part -------------- A non-text attachment was scrubbed...
