* ArmPkg: ArmScmiDxe - convert .h to from 8859-x to 7-bitLeif Lindholm2019-10-041-1/+1
| | | | | | | | | | | | A paragraph sign in a comment came from some ISO8859 encoding, convert it to the word "section" to remain 7-bit safe, since we're not actually doing anything special.

* ArmPkg/ArmScmiDxe: Add clock enable functionJeff Brasen2018-12-213-0/+70
| | | | | | | | | | | | | | | | Add function to allow enabling and disabling of the clock using the SCMI interface. Add gArmScmiClock2ProtocolGuid to distinguish platforms that support new API from those that just have the older protocol. SCMI_CLOCK2_PROTOCOL also adds a version parameter to allow for future changes. It is placed after the functions that are present in the existing protocol to allow SCMI_CLOCK2_PROTOCOL to be cast to SCMI_CLOCK_PROTOCOL so that only a single implementation of those function are needed.

* ArmPkg/ArmScmiDxe: Dynamically allocate buffer for protocol idsGirish Pathak2018-06-223-12/+21
| | | | | | | | | | | | Dynamically allocate the buffer to receive the SCMI protocol list. This makes MAX_PROTOCOLS redundant, so it is removed. It also fixes one minor code alignment issue and removes an unused macro PROTOCOL_MASK.

* ArmPkg/ArmScmiDxe: Fix ASSERT error in SCMI DXEGirish Pathak2018-06-222-21/+23
| | | | | | | | | | | | | | | | | | | | | This change fixes a bug in the SCMI DXE which is observed with the upcoming release of the SCP firmware. The PROTOCOL_ID_MASK (0xF) which is used to generate an index in the ProtocolInitFxns is wrong because protocol ids can be anywhere in 0x10 - 15 or 0x80 - FF range. This mask generates the same index for two different protocols e.g. for protocol ids 0x10 and 0x90, which causes duplicate initialization of a protocol resulting in a failure. This change removes the use of PROTOCOL_ID_MASK and instead uses a list of protocol ids and their initialization functions to identify a supported protocol and initialize it.

* ArmPkg: Introduce SCMI protocolGirish Pathak2018-04-2311-0/+2046
This change introduces a new SCMI protocol driver for Arm systems. The driver currently supports only clock and performance management protocols. Other protocols will be added as and when needed. Clock management protocol is used to configure various clocks available on the platform e.g. HDLCD clock on the Juno platforms. Whereas performance management protocol allows adjustment of various performance domains. Currently this is used to evaluate performance of the Juno platform.
