imx-common: timer: support i.MX6DQPlus

2016-05-24T12:59:56Z

To i.MX6DQPlus, osc can be choosed as the source of gpt, so add i.MX6DQPlus support in gpt_has_clk_source_osc. Signed-off-by: Peng Fan Cc: Stefano Babic

imx-common: timer: clean up code

2015-10-30T13:59:43Z

We can reuse common functions in lib/time.c, but not reimplement functions in imx-common/time.c. Only keep timer_init ,get_tbclk and implement timer_read_counter in imx-common/time.c. Signed-off-by: Peng Fan Cc: Stefano Babic Cc: Fabio Estevam

imx: mx6 correct is_soc_rev usage

2015-06-27T16:16:31Z

is_soc_rev should return a bool value, so use "==", but not "-", change (is_soc_rev(CHIP_REV_1_0) > 0) to (soc_rev() > CHIP_REV_1_0). This patch also add space between "&" for cpu_type(rev) macro. Signed-off-by: Peng Fan

imx6: Added DEK blob generator command

2015-03-02T08:57:06Z

Freescale's SEC block has built-in Data Encryption Key(DEK) Blob Protocol which provides a method for protecting a DEK for non-secure memory storage. SEC block protects data in a data structure called a Secret Key Blob, which provides both confidentiality and integrity protection. Every time the blob encapsulation is executed, a AES-256 key is randomly generated to encrypt the DEK. This key is encrypted with the OTP Secret key from SoC. The resulting blob consists of the encrypted AES-256 key, the encrypted DEK, and a 16-bit MAC. During decapsulation, the reverse process is performed to get back the original DEK. A caveat to the blob decapsulation process, is that the DEK is decrypted in secure-memory and can only be read by FSL SEC HW. The DEK is used to decrypt data during encrypted boot. Commands added -------------- dek_blob - encapsulating DEK as a cryptgraphic blob Commands Syntax --------------- dek_blob src dst len Encapsulate and create blob of a len-bits DEK at address src and store the result at address dst.

imx: gpt: Add High frequency clock source support for GPT

2014-11-03T10:21:41Z

Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set, the GPT will select a high frequency clock as clock source. Otherwise, the GPT will stay to use 32Khz OSC as clock source. In the implementation, since only the GPT on i.MX6 series provide the clock source option for 24Mhz OSC. For others (only i.MX5 and i.MX6 compile the driver), if the configuration is set, the perclk will be selected as clock source. MX6Q/D Rev 1.0 and MX6SL are special in the implementation, because they don't have the 24Mhz OSC clock source option, so also select the perclk for them. For MX6SL, we will set the OSC 24Mhz to perclk in CCM, so eventually the clock comes from OSC 24Mhz. Signed-off-by: Ye.Li

imx-common: timer: fix 32-bit overflow

2013-03-20T10:36:11Z

The i.MX6 common timer uses the 32-bit variable tbl (time base lower) to record the overflow of the 32-bit counter. I.e. if the counter overflows, the variable tbl does overflow, too. To capture this overflow, use the variable tbu (time base upper), too. Return the combined value of tbl and tbu. lastinc is unused then, remove it.
